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 she succeeded in decreasing methylation of histone tails. Which of the following results would she most likely see?
A)increased chromatin condensation
B)decreased chromatin concentration
C)abnormalities of mouse embryos
D)decreased binding of transcription factors
E)inactivation of the selected genes

Question

Methylation of histone tails is associated with increased chromatin condensation and transcriptional repression. Therefore, decreasing methylation would result in decreased chromatin condensation and potentially increased gene expression.
