t24 human bladder carcinoma oncogene is an activated form of the normal human homologue of balb- and harvey-msv transforming genes
A transforming gene isolated from T24 human bladder carcinoma cells is closely related to the BALB murine sarcoma virus (MSV) onc gene (v-bas).
The 1.2-kbp polyadenylated transcript that this transforming gene produces, which contains v-bas-related sequences, is expressed from a 4.6 kilobase pair (kbp) area where it is localized. Moreover, higher amounts of a similar protein were found in T24 cells using antisera that are known to target the immunologically related onc gene products of the BALB- and Harvey-MSVs.
By using restriction enzymes and heteroduplex analysis, it was discovered that the T24 oncogene could not be distinguished from the v-bas normal human homologue. These findings suggest that the normal human v-bas homologue has been activated as a human transforming gene by relatively minimal genetic changes.

What is gel electrophoresis?
A laboratory technique called gel electrophoresis is used to divide combinations of DNA, RNA, or proteins based on their molecular sizes. In gel electrophoresis, the molecules that need to be separated are forced through a gel that has tiny holes by an electrical field.It involves an electrical field, specifically one that is applied such that the gel has a positive charge on one end and a negative charge on the other. Negatively charged molecules like DNA and RNA will be drawn to the positively charged end of the gel. However, because proteins lack a negative charge, they must first be combined with sodium dodecyl sulfate, a detergent, in order to separate them using this method. The proteins are given a linear structure and a negative charge during this process, enabling them to move toward the gel's positive end and be separated. Finally, after utilizing it to separate the DNA, RNA, or protein molecules, bands representing of different molecular sizePrinciple of gel electrophoresis:
Since DNA is negatively charged, it will move toward the positively charged electrode when an electric current is supplied to the gel. The DNA fragments are organized in size order because shorter DNA strands travel through the gel more quickly than longer ones.
Steps in gel electrophoresis:

Though the parents have blood group A and B , still their son is of blood group and colorblind aswell is possible due to codominance.
What is codominance?
In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.
Red blood cells with blood type A have a specific antigen (class of protein) on their membrane. Red cells in type B blood have a unique antigen on their membrane, but neither is present in type O blood.
The type O gene is "recessive" because if you only have one copy of the O gene and one copy of the A gene, you will still have A antigens on your cell membranes. You must have two O parent cells in order to belong to group O. However, group O continues to be more prevalent merely because it is the ancestor form.
The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female). Males only get one X chromosome, thus even while the recessive trait is present, there isn't another X chromosome that would provide a dominant trait of normal color vision. On the other hand, most female offspring have a propensity to develop into what are known as "carriers," which are people who have the recessive gene (color blindness) as well as the dominant gene (normal color vision), resulting in the expression of the dominant feature.

What is natural selection?
One method of evolution is natural selection. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.
As a result of natural selection, reproductive individuals pass on genetic changes that are advantageous to their progeny's survival. New creatures are created as a result, and they have a higher chance of surviving and reproducing. For instance, giraffes have an advantage over other species because of their long necks, which have evolved to allow them to eat leaves that other species cannot. Longer-necked individuals were able to reproduce and pass on their trait to the next generation because they had access to better food sources. Shorter-necked individuals would be less likely to survive and pass on their genes as a result of having less food availability.
The plant that grows larger has seeds adapted to the environment, which proliferate more readily than seeds from other plants.
One of the two fish species that consume the same food is more adapted and can thus gather more food.
Favorable male lions will be able to compete with other male lions for female mates and will be preferred over them because of their superior adaptation and physical characteristics.
Natural selection, also referred to as "survival of the fittest," is a phenomenon in which organisms that are best adapted to a particular environment are chosen while inferior organisms are weeded out.
In all three cases, biological evolution will take place as a result of selection favoring organisms that are better adapted to their surroundings and capable of competing with other species for survival.

c) RNAi
d) tRNA
The correct option among the following was DNA Methylation.
define DNA Methylation ?
A biological process called DNA methylation involves the addition of methyl groups to the DNA molecule. Without altering the sequence, methylation can modify the activity of a DNA region. DNA methylation often suppresses gene transcription when it occurs at a gene promoter. DNA methylation plays an important role in a variety of critical processes in mammals, including ageing, cancer, X-chromosome inactivation, genomic imprinting, and transposable element suppression.
Adenine and cytosine are the two nucleobases on which natural, enzymatic DNA methylation occurs as of 2016. N6-methyladenine[1], 5-methylcytosine[2], and N4-methylcytosine are the modified bases. [3]
The DNA nucleotide cytosine is methylated to create 5-methylcytosine at position 5 on the pyrimidine ring. This is the same place that separates thymine from the homologous RNA base uracil, which has no methyl group. 5-Methylcytosine undergoes spontaneous deamination and is changed into thymine. A T:G mismatch emerges from this. If A is substituted for G, the original C:G pair becomes a T:A pair, thus altering a base and producing a mutation. Repair mechanisms then fix it back to the original C:G pair.

Meissner corpuscle or tactile corpuscle is the tactile receptor found in the dermal papillae.
Professor Georg Meissner and Professor Rudolf Wagner initially identified Meissner corpuscles, often referred to as Wagner-Meissner corpuscles or tactile corpuscles, as a subset of mechanoreceptors in 1852. These unique encapsulated nerve terminals transmit low-frequency vibration and fine touch sensations to the central nervous system from the dermal papillae of glabrous skin (CNS). Meissner corpuscles are crucial for somatosensory acuity, particularly in the palmar skin and digital extremities. This has clinical implications for diabetic neuropathy, peripheral neuropathy, and the aging-related deterioration of dermatological tactile sense.
Meissner corpuscles are ellipsoid mechanoreceptors that are situated 150 micrometres superficially within the dermal papillae. The corpuscles have a long axis that is perpendicular to the skin's surface and are between 20 and 40 micrometres in diameter and 80 and 150 micrometres in length. Less than three corpuscles per papilla, with one corpuscle every two to four dermal papillae. The site of genesis affects the receptors' size and density.

The statement is False, i.e. single-cell profiling of tumor heterogeneity and the microenvironment in advanced non-small cell lung cancer.
Tumor cells can vary in their cellular shape, gene expression, metabolism, motility, proliferation, and metastatic potential, among other physical and behavioral characteristics. Tumor heterogeneity is the term for this phenomenon. This phenomenon has an impact on tumors both within them and between them (inter-tumor heterogeneity) (intra-tumour heterogeneity). Every time a cell multiplies, whether it be healthy or cancerous, a few mutations are picked up, creating a diverse population of cancer cells. This minor degree of intra-tumor heterogeneity is a clear outcome of the flaw in DNA replication. Because cancer cells vary greatly in their characteristics, creating effective treatment programs is substantially more difficult. But research into recognizing and explaining heterogeneity can help us better understand the origins and progression of disease. This could then serve as guidance for the creation of more complex treatment plans that account for heterogeneity to yield higher efficacy. A population of tumor cells only contains a small subset of cells that are tumorigenic, claims the cancer stem cell paradigm (able to form tumours). These cells, which have the ability to self-renew and differentiate into progeny that are not tumorigenic, are known as cancer stem cells (CSCs).

What is urine?Urine is the wastewater that excretes from the body. Human pee is composed of 95 percent water. Minor amounts of urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulfate, ammonium, and phosphate, as well as other ions and molecules, make up the remaining components. The filtrate contains components such as glucose, amino acids, Na+, and so on.
Therefore, the correct option is b. Amino Acids and c. Glucose.

Which condition would be most likely to turn off this abnormally active signaling pathway?.
Conditions that may turn off abnormally active signaling pathways are the addition of a drug that prevents the final kinase from interacting with its target protein in the nucleus.
The MAP kinase pathway is a series of proteins in cells that link signals from receptors on the cell surface to DNA in the cell nucleus. Signaling begins when growth factors bind to receptors on the cell surface. The final stage is when the DNA in the cell nucleus has expressed a protein and produces changes in the cell, such as cell division.
The pathway involves several proteins including the MAP kinase which engages by adding a phosphate group to adjacent proteins and acts as an on-and-off switch.
This question is incomplete, the complete question is:
Normal signaling works with a Ras protein acting downstream of a receptor kinase. You examine a cell line in which Ras is always activated even in the absence of a signaling molecule. This causes constant activation of the kinases in the MAP kinase pathway. Which of the following conditions would be MOST likely to turn off this abnormally active signaling pathway?
