The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?
Answer:
The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).
Explanation:
Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.
In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.
In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..
Describe the normal process of osteogenesis for compact and spongy bone using the three different types of bone cells and their functions
Answer:
Osteoblasts penetrate the disintegrating cartilage and replace it with spongy bone. This forms a primary ossification center. Ossification continues from this center toward the ends of the bones. After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity.
what must be true about two objects if heat is flowing between them
Answer:
The objects must be the same temperature.
Explanation:
if heat is flowing between two objects, so both the objects must have the same temperature because the heat in object 1 passes to the object 2 due to the conduction property present in these objects. The heat flows from one body to another body until both have the same amount of heat energy as well as temperature so that's why we can say that both objects must be the same temperature.
Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

Genes:
A. in plants exist only in some individuals
B. they determine the structural and functional characteristics of each individual
C. they determine only the functional characteristics of each individual
D. they determine only the characteristics structural of each individual
E. do not exist in prokaryotes
Answer:
B. They determine the structural and functional characteristics of each individual
Explanation:
Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.
Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.
Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.
So, the correct answer is B.

An inflatable balloon with the volume of 0.75 L at 303 K was placed inside the freezer where the temperature is 263 K. Find out what will happen to the volume of the balloon if the pressure remains constant.
Answer:
Final volume, V2 = 0.66 Litres
Explanation:
Given the following data;
Initial volume = 0.75 L
Initial temperature = 303 K
Final temperature = 263 K
To find out what will happen to the volume of the balloon if the pressure remains constant, we would use Charles' law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles' law is given by the formula;
[tex] VT = K[/tex]
[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Where;
V1 and V2 represents the initial and final volumes respectively.T1 and T2 represents the initial and final temperatures respectively.Making V2 as the subject formula, we have;
[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]
[tex] V_{2}= \frac{0.75}{303} * 263 [/tex]
[tex] V_{2}= 0.0025 * 263 [/tex]
Final volume, V2 = 0.6575 ≈ 0.66 Litres

2. Mutations within a____may lead to major changes in______for example, ita Hox gene is attected. Moreover, if a transposable element inserts here, it may lead to a decreased or increased_____. This may impact the organism and if passed on to the offspring, become____. The result of these events may eventually lead to increased fitness and formation of new species.
Answer:
1. Mutations in protein-coding genes and regulatory DNA contribute to evolution if the organism carrying them survives and_c. reproduce. Mutations in a_a. gene lead to different effects. For example, a mutation may change the _h. function of the protein or the protein will no longer be produced.
2. Mutations within a_i. regulatory sequence may lead to major changes in_g. body form, for example, if a Hox gene is affected. Moreover, if a transposable element inserts here, it may lead to a decreased or increased_d. protein production. This may impact the organism and if passed on to the offspring, become_e. inherited. The result of these events may eventually lead to increased fitness and the formation of new species.
Explanation:
Mutations can be defined as genetic changes (nucleotide changes) in the genome sequence of an organism. Mutations can be beneficial, neutral or deleterious (depending on their effects on the adaptive fitness of the individual). Mutations that occur in the somatic (body cells) will not be inherited, whereas mutations in the germinal (gamete) cells can be passed on to the next generations. Moreover, Hox genes are major developmental regulators involved in a wide variety of aspects of animal development. In consequence, changes in the expression level of Hox genes caused, for example, through 1-mutations of their regulatory sequences, such as promoter sequences, or 2-the insertion of transposable elements, may lead to conspicuous phenotypic changes by affecting protein production. Eventually, these mutations may confer an adaptive advantage.

A scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. What molecule has likely contaminated his mixture?
nucleotide
protein
DNA
RNA
Answer:
RNA
Explanation:
A ribonucleic acid (RNA) is one of two types of nucleic acid made up of nucleotide subunits. RNA is a single stranded molecule unlike DNA, which is double stranded. The nucleotide unit of nucleic acids is composed of a nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil), a pentose sugar (ribose and deoxyribose) and a phosphate group.
One of the key structural differences between RNA and DNA is that RNA contains URACIL nitrogenous base instead of THYMINE in DNA.
According to this question, a scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. This illustrates that the contaminating molecule is a specific type of nucleic acid called RNA.
