The correct sequence in which the proteins are synthesized is DNA --> RNA --> Protein (B).
First the DNA is transcribed into RNA and then by translation RNA is converted into protein.
<h3>Protein Synthesis</h3>
- Protein synthesis is the process of making protein molecules.
- This process includes two processes, transcription and translation.
- In transcription, the DNA act as a template to produce RNA. This is a three-step process, initiation, elongation, termination.
- In translation, the RNA with the help of codons produces protein. This is also a three-step process: Initiation, elongation, and termination.
Thus, that's how proteins are made. And it is a repeated process.

Answer:
C. A1A2, A1A3
Explanation:
This question depicts a gene coding for coloration in a flowering plant. The gene is controlled by multiple alleles, three specifically. The alleles are labelled A1, A2, and A3, with each coding for it's own respective trait.
According to the question, A1 is dominant over A2 and A3 i.e. A1 will always mask the phenotypic expression of A2 and A3 and express itself. Also, A2 is dominant over A3 i.e. A2 will always mask the phenotypic expression of A3. This overall means that the trait encoded by allele A3 will only be expressed when the same alleles are present.
To the question; since A1 is dominant over the other two alleles (A2 and A3), it will be phenotypically expressed ahead of them in a heterozygous state with both alleles. That is, A1A2 genotype will give rise to a phenotype encoded by A1. Also, A1A3 will produce a phenotype encoded by A1. Hence, genotypes A1A2 and A1A3 will express the same phenotypes.
A2A2 and A3A3 will express different phenotypes since they are both in a same alleles condition. Likewise for A1A1 and A3A3. A2A3 and A1A3 genotypes will express different phenotypes encoded by A2 and A1 respectively since they are both dominant over A3.
The correct answer is centrosome.
<span>The centrosome is the main microtubule organizing centre of the animal cell and it is involved in the regulation of cell-cycle progression. During the mitosis, the centrosome microtubules can interact with the chromosomes to build the mitotic spindle.</span>
If A is dominant allele, and a is recessive allel, than:
p is frequency of A allele, q is a frequency of a allele, p2 is a frequency of homozygous dominant genotype, 2pq is frequency of heterozygous genotype and q2 is frequency of homozygous recessive genotype.
If the population is in Hardy-Weinberg equilibrium; p+q=1
p=0.15 q=1-0.15=0.85
2pq=2*0.15*0.85=0.255~26%
