Which of the following adds to the complexity of gene expression in eukaryotic cells?

Question

Quizplus · Accepted Answer

A) Alternative splicing removes different introns from mRNA, thus allowing for the production of multiple protein isoforms from a single gene.
B) Noncoding DNA, such as enhancers and silencers, can control the timing and amount of gene expression by interacting with transcription factors and RNA polymerase.
C) Chromosomal rearrangements can alter the number and organization of genes, which can lead to changes in phenotype. Therefore, all of these factors contribute to the complexity of gene expression in eukaryotic cells.
