Question

11. (Problem 37) How are epigenetic marks thought to be interpreted into chromatin structure? Epigenetic marks affect chromatin structure and gene expression. Since epigenetic marks are inherited, chromatin structure is also inherited Epigenetic marks have no affect on chromatin structure and gene expression. O The binding of enhancer proteins to chromatin affects the shape of chromatin in the next generation Unmethylated histones alter chromatin structure, but methylated histones have no affect on chromatin structure. The pattern of unmethylated histones drives the structure of chromatin from one generation to the next O Histone acetylation patterns destabilize chromatin structure from one generation to the next.

Explanation / Answer

DNA Methylation and histone modification are the epigenetic marks. These marks on histone and DNA could bring change in chromatin structure and gene expression. These epigenetic marks are inheritable along with chromatin structure.

So first option is correct i.e. “Epigenetic marks affect chromatin structure and gene expression since epigenetic marks are inherited, chromatin structure also inherited”
