D.VACUOLE

Explanation:

Answer:

1. The difference between the normal hemoglobin protein DNA sequence and the sickle cell hemoglobin DNA sequence is a base to base shift, in this case adenine (GAG) to thymine (GTG).

2. The difference affects the amino acid sequence of the protein by replacing glutamic acid (Glu) with valine (Val).

Explanation:

In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the amino acid sequence of globine β, incorporating valine instead of glutamic acid. This represents a molecular mutation - point mutation - by subtitution, which corresponds to missense mutation.

Normal hemoglobin protein in a RBC

DNA                 CTG ACT CCT GAG GAG AAG TCT

Amino acids     Leu  Thr   Pro   Glu   Glu   Lys   Ser

Sickle cell hemoglobin protein in a RBC

DNA                 CTG ACT CCT GTG GAG AAG TCT

Amino acids     Leu  Thr   Pro   Val   Glu   Lys   Ser

When GAG is transcribed to mRNA, the CUC codon is obtained, which codes for glutamic acid. Thymine substitution causes the DNA sequence to change to GTG, which is transcribed as CAC, the codon that encodes the amino acid valine. The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.

Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. In contrast, meiosis serves a single function in the human body that is the creation of gametes.

The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.

Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.

Grow in the absence of signals instructing them to do so in cancer cells. Only when they get such signals do normal cells expand. Disregard cues that would typically instruct cells to cease dividing or die.

Aneuploidy is a condition when there are either too many or too few chromosomes in the daughter cells produced during mitosis.

Thus, this is the overall purpose of mitosis and meiosis.

1. The overarching goal of mitosis is to ensure cell division and the transfer of genetic material to daughter cells for tissue repair, growth and development.

2. To maintain genetic integrity, DNA replication is necessary prior to cell division.

3. Cancer cells have uncontrolled growth, escape cell death and lack contact inhibition, whereas normal cells have controlled cell division, experience programmed cell death and show contact inhibition.

4. The disorders in humans can result from errors in the cell cycle. Diseases such as Down syndrome are caused by abnormal chromosomes. Gene changes can affect the development of cancer.

Meiosis produces gametes for sexual reproduction, while mitosis assures cell division for growth, development, and tissue repair. Accurate transmission of genetic information and preservation of genetic integrity in daughter cells depend on DNA replication prior to cell division.

Whereas cancer cells have uncontrolled proliferation, escape from cell death, and lack contact inhibition, normal cells have regulated division, programmed cell death, and appear to have contact inhibition. Human disorders such as chromosomal abnormalities (such as Down syndrome), gene mutations that cause cancer, errors in DNA replication or repair that cause genetic disorders, and cell cycle control that leads to uncontrolled cell division and tumor formation, all of which Mistakes made during this can have consequences. cell cycle.

Answer:

C. The organs in an organ system work together to perform a specific function.

Explanation:

The definition of an organ system is a "group of organs that work together as a biological system to perform one or more functions". Each organ in a system does a different job in order to achieve the same goal. For example, the stomach breaks down food, and the intestines gather nutrients but the goal of both is to digest food.

Answer:

T always pairs with A

Explanation:

I think so I'm super sorry if its wrong :)

According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.

Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.

Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs

Although they keep the two strands of DNA together, they are not strong enough to withstand replication.

Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.

The correct answer would be - to communicate unambiguously globally.

Explanation:

In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.

Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.
