Question is a multiple choice question.
Answer:
Question 1. The major advantage of using artificial chromosomes such as YACs and BACs for cloning genes is that:
Answer:
(C)
Explanation:
YACs and BACs can carry much larger DNA fragments than ordinary plasmids can.
Question 2. Simply inserting an entire eukaryotic gene into a prokaryotic expression system will most likely not work for the following reason.
Answer:
(B)
Explanation:
Prokaryotes lack introns
Your answer is C. The pancreas produces enzymes that break down carbohydrates, proteins, and fats
Answer:
Frequency of the B3 allele 
Explanation:
The allele frequencies in a given population remain constant which means that every generation will have the same gene pool across the generations. As per Hardy Weinberg’s first equilibrium equation, the sum of frequency of all the alleles at a given locus is equal to one
Thus, if "p" represents the frequency of B1 allele and "q" represents the frequency of B2 allele and "r" represents the allele for B3 allele. Then, sum or "p", "q" and "r" is equal to one.

Substituting the given values, we get -
