Question

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. This means that Histone methyltransferase does what?

Answer 1

Histone methyltransferases are enzymes that methylate histone proteins, and the research team found that inhibiting histone methyltransferase activity decreases the transcription of gene R. This suggests that histone methyltransferases play a role in regulating gene expression, likely by modifying the chromatin structure to either activate or repress gene transcription.
