DNA is <span>deoxyribonucleic acid, a carrier of genetic information. mRNA are molecules that carry a portion of the DNA code to other parts of the cell for processing.

Answer:
Option B, No
Explanation:
Complete question is as follows -
You have spent time working with a population of beetles. Sexually mature males range in size from 2-6 cm in length. You realize that the females only mate with males that measure less than 3 cm long. If you measured allele frequencies at a single gene (locus) that contributes to overall length, would you expect this population to be in H-W equilibrium from one generation to the next?
Select one:
a. Yes
b. No
Solution -
No, because Hardy Weinberg’s equilibrium theory is not applicable in practical scenario as it assumes that H-W equilibrium persists from one generation to the other only when these is no disturbing factor . These disturbing factors include – natural selection, non-random mating, genetic drift, gene flow and mutations. Since this theory works only in an idealized state where no such disturbances occur, it is very difficult to say that the beetle population can remain in H-W equilibrium. Also the females in the beetle population are selecting the males for mating thereby exhibiting sexual selection. Hence, H-W equilibrium will not be applicable.
Hence, option B

Three questions that focuses on the cause and effect relationship between the genetic code and gene expression, mechanisms of gene regulation and/or the role of DNA segments that is not involved in coding the proteins are:
i. Illustrate the process of translation and explain it with the help of a diagram.
ii. What are codons? Name the stop codons in eukaryotes.
iii. What are exons and introns? Explain what happens to the introns during the process of transcription and translation?
