Question

_______ of the Drosophila sequence is composed of TEs and _____ is heterochromatic regions that do not include genes.

(a) one-fourth, one-third

(b) one-fifth, one-fourth

(c) one-sixth, one-eighth

(d) one-sixth, one-third

This question was posed to me in quiz.

The question is from Sequence Assembly and Gene Identification topic in portion Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

The correct answer is (d) one-sixth, one-third

To explain: Hence, in the euchromatic regions, the gene density in the Drosophila genome is one gene per 9 kb. Despite the fact that the lower number of predicted genes in Drosophila is smaller than that of the other genomes, the amount of functional diversity, as evidenced by protein family representation, is similar.
