Which statement about genomes is true?
A) The genome sizes of all plants are smaller than those of all animals.
B) Humans have the largest genome size of all animals.
C) Most of the bacterial genome is noncoding.
D) The variation in genome size among animals is greater than the variation in the number of genes.
E) Most of the DNA in humans codes for proteins.

Question

Quizplus · Accepted Answer

The variation in genome size among animals is much greater than the variation in the number of genes. For example, the genome of an amoeba is much larger than that of a human, despite humans having significantly more genes. Additionally, while some bacterial genomes are almost entirely noncoding, others contain mostly coding DNA. Therefore, options A, B, C, and E are incorrect.
