Chapter 15.2, Problem 1CC
Summary Introduction
To determine:
The effect of histone acetylation and DNA methylation on gene expression.
Introduction:
Gene expression may be done by the transcription of DNA into mRNA and formation of polypeptide chains by the translation process. This process is termed as ‘central dogma’.
The amount of protein that is produced by gene is must be control by the cell.
Gene expression associates histone acetylation, and DNA methylation is associated with lack of gene expression.
