Why might the cricket genome have eleven times as many base pairs as that of Drosophila melanogaster?
A) Crickets have higher gene density.
B) Drosophila are more complex organisms.
C) Crickets must have more noncoding DNA.
D) Crickets must make many more proteins.

Question

Quizplus · Accepted Answer

The higher number of base pairs in the cricket genome suggests the presence of a larger amount of noncoding DNA, which may include regulatory sequences, repetitive elements, and structural components such as telomeres and centromeres. This noncoding DNA may not directly code for proteins, but it plays important roles in gene expression and genome function. The other answer choices, such as higher gene density or complexity, are not necessarily linked to genome size.
