Question

What is epigenetics? chemical modifications such as histone acetylation that impact the structure of chromatin but do not cause a change in phenotype mechanisms by which changes in phenotype are maintained in a cell or are passed to other cells or future generations without a change in the base sequence of DNA O chemical changes such as DNA methylation that alter the nucleotide sequence but not the overall packaging of the DNA maintained across numerous cell divisions changes that occur within the nucleotide sequence of noncoding regions but stll have the o mechanisms by which changes in phenotype occur within a cell but are unable to be o

Explanation / Answer

Answer:

Mechanism by which changes in phenotype are maintained in a cell or are passed to other cells or future generations without a change in the base sequence of DNA.

Explanation:

Epigenetics is the study of heritable changes in gene expression that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes.
