The Neurospora genome is quite compact, lacking many of the noncoding DNA sequences that occur in humans and many other eukaryotes. Which of the following are probable benefits of the compactness of the genome?

Question

Quizplus · Accepted Answer

A compact genome means that there are fewer DNA bases that need to be replicated during cell division. This saves the organism energy during this process.

Answer: B
 A compact genome may make it more difficult for viruses to insert themselves because there are fewer noncoding regions for them to integrate into.

Answer: C and D are not probable benefits of a compact genome. Less genetic variation may actually be a disadvantage, as it reduces the potential for adaptation to changing environments, and the size of spores is not directly related to genome size.
