Genomes of Species in Both Bacteria and Archaea Show a Strong

Question

Genomes of species in both Bacteria and Archaea show a strong correlation between genome size and
A) noncoding RNA.
B) codon bias.
C) number of ORFs.
D) number of introns.

Accepted Answer

Genome size in both Bacteria and Archaea correlates strongly with the number of open reading frames (ORFs), which are the sequences of DNA that can be translated into proteins. This is likely because larger genomes tend to have more genetic information and therefore more potential genes, leading to a higher number of ORFs. Noncoding RNA, codon bias, and introns may also play a role in genome size, but they do not show as strong a correlation as the number of ORFs.
