Question

Which of the following are examples of epigenetics?

1) DNA methylation
2) Covalent histone modification
3) DNA mutation
4) Localization of histone variants
5) Chromatin remodeling
6) DNA translocation

Answer 1

Epigenetics examples include DNA methylation, covalent histone modification, localization of histone variants, and chromatin remodeling.

Step-by-step explanation:

The examples of epigenetics are:

1. DNA methylation: This is the addition of methyl groups to the DNA, which can suppress transcription.
2. Covalent histone modification: Chemical modifications of histone proteins bound to chromosomal DNA, such as acetylation or methylation, can affect gene expression.
3. Localization of histone variants: The presence of different histone variants can influence chromatin structure and gene regulation.
4. Chromatin remodeling: This refers to changes in the structure and accessibility of chromatin, which can impact gene expression.
