Answer:

all of the above

Explanation:

Epigenetic alterations are modifications of the genome transmitted during cell division, which do not involve changes in the DNA sequence, are hereditary and are capable of modifying gene expression. In addition, they are temporary modifications that allow DNA to be transcribed and have the ability to move histones to open or close a chromosomal region. There are three main mechanisms of epigenetic alterations: DNA methylation, histone modifications and genomic imprinting.

Epigenetic changes allow DNA to be transcribed, move histones to open or close a chromosomal region, and are temporary. These are important because, they are able to change genes by modifying gene expression and allowing them to be transcribed.
