A researcher found a method she could use to manipulate and quantify phosphorylation and methylation in embryonic cells in culture.
-In one set of experiments using this procedure in Drosophila, she was readily successful in increasing phosphorylation of amino acids adjacent to methylated amino acids in histone tails. Which of the following results would she most likely see?

Question

Quizplus · Accepted Answer

Increased phosphorylation of amino acids adjacent to methylated amino acids in histone tails is likely to decrease chromatin condensation. This is because phosphorylation and methylation are both modifications that affect the structure and function of chromatin, and increasing phosphorylation can counteract the compacting effects of methylation.
