Question
Epigenetic changes are those changes in the expression of genes which are caused by any other reason except the change in the nucleotide sequence. The reason could be DNA methylation, histone acetylation, genomic imprinting, histone variant localization. Hence option a, d, e, g are correct.

The first level of gene regulation occurs along the chromosome, through chemical modifications of the DNA or histones. How do these chemical modifications cause changes in gene expression? Select all that apply a. The chemical modifications to DNA could prevent the removal of introns from the mRNA b. The chemical modifications to DNA could activates enzymes that add chemical modifications to histones c. The chemicalodifications to DNA and histones could affect the binding of ribsomea to mRNA to initiate translation...
