If natural selection over the time period of Eukaryote evolution has favored a DNA architecture in Eukaryotes that keeps genes turned off except when needed,this structure would be _____.
A)nucleosomes
B)terminators
C)exons
D)introns

Question

Quizplus · Accepted Answer

Nucleosomes are responsible for organizing DNA in eukaryotes and are involved in regulating gene expression by keeping genes turned off except when needed. This allows for selective activation of genes when necessary, which is advantageous for survival and adaptation. Terminators, exons, and introns are not directly involved in this process of regulating gene expression.
