Histone methyltransferases are a class of enzymes that methylate certain amino acid sequences in histone proteins. A research team found that transcription of gene R decreases when histone methyltransferase activity is inhibited. Which scientific claim is most consistent with these findings?
A) DNA methylation inhibits transcription of gene R.
B ) Histone modifications of genes are usually not reversible.
C ) Histone methylation condenses the chromatin at gene R so transcription factors cannot bind to DNA.
D) Histone methylation opens up chromatin at gene R so transcription factors can bind to DNA more easily.
