B-DNA can adopt the Z-DNA conformation under certain physiological conditions. Z-DNA may play a role in gene expression; specifically, it could play a role in the regulation of particular genes and the organization of chromosomes.

What is B DNA?

B-DNA is a double-stranded DNA structure that is right-handed and helical. This is the most common DNA conformation, which is known for its flexibility and ease of unwinding. Base pairs are oriented perpendicularly to the central axis of the molecule in this DNA conformation, and it has a diameter of 20 Angstroms.

What is Z DNA?

Z-DNA is a left-handed helix with a zigzag pattern that is narrower and elongated. In the Z-DNA conformation, the DNA backbone is much more twisted, with base pairs that are tilted relative to each other. This DNA structure is less common than B-DNA and is characterized by a more rigid structure than other DNA conformations.

What is gene expression?

Gene expression is the process by which information stored in DNA is used to synthesize gene products like proteins. A gene is a segment of DNA that contains information for the synthesis of a specific protein or RNA molecule, and its expression is regulated by various factors. Gene expression regulation is a highly complex process that involves many regulatory mechanisms to ensure that only the necessary genes are expressed at the right time and in the right amount.

DTTP (deoxythymidine triphosphate) acts as an allosteric effector.

The correct option is A. Ribonucleotide Reductase (RNR) is an enzyme involved in the synthesis of deoxyribonucleotides, which are essential building blocks for DNA replication and repair.

The activity and regulation of RNR are critical for maintaining the balance of deoxyribonucleotide pools in the cell. In RNR, dTTP (deoxythymidine triphosphate) acts as an allosteric effector. It binds to the selectivity site of RNR and stimulates the binding of dATP (deoxyadenosine triphosphate) to the activity site.

This binding event promotes the catalytic activity of RNR, facilitating the conversion of ribonucleotides to deoxyribonucleotides. By regulating the levels of dTTP, RNR ensures the proper balance of deoxyribonucleotides required for DNA synthesis and maintenance.

It is possible to use other promoters to create a resistant corn plant, but it would depend on the specific characteristics of the promoter and the trait of interest.

The CaMV 35S promoter, which is commonly used to create transgenic crops, is just one of many promoters that can be used to express foreign genes in plants. Other promoters, such as the ubiquitin promoter or the maize alcohol dehydrogenase (Adh1) promoter, have also been used successfully to create transgenic plants with desirable traits. In order to create a resistant corn plant, scientists would need to identify a promoter that is specific to the gene or genes responsible for the desired resistance, and then use that promoter to express those genes in the corn plant. However, it is important to note that the creation of transgenic plants is a complex and highly regulated process, and the safety and environmental impact of such plants must be carefully evaluated before they are approved for commercial use.

Following Hardy-Weinberg equilibrium equations, and considering a diallelic gene, if p = 0.37, then q = 0.63. The frequency of the recessive allele -q- is 0.63.

To answer this question, we will assume Hardy-Weinberg equilibrium.

The Hardy-Weinberg equilibrium is a theory that states that a population in equilibrium will express the same allelic and genotypic frequencies through several generations.

Assuming a diallelic gene,

• The frequency of the dominant allele p(X) is p

• The frequency of the recessive allele p(x) is q

The addition of the allelic frequencies equals 1

p + q = 1.

• p² (Homozygous dominant genotypic frequency),

• 2pq (Heterozygous genotypic frequency),

• q² (Homozygous recessive genotypic frequency).

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.

In the exposed example, we have a diallelic gene. We already know the frequency of the dominant allele (p = 0.37) and now we need to know the frequency of the recessive allele (q = ?). All we need to do is to clear the following equation,

p + q = 1

0.37 + q = 1
