What is the epigenome? the complete set of noncoding DNA possessed by an individual organism the sequence of DNA methylation sites within the genome of an organism the complete set of sequences that Xist interacts with in an organism the sequence differences within the coding regions when comparing two different individuals of the same species the complete set of chromatin modifications possessed by an individual organism

Answer: 1 the complete set of sequences that Xist interacts with in an organism

Explanation:

The epigenome is the collection of all the epigenetic marks in the DNA of a single cell, thus referring to the complete set of modifications that occur in the chromatins that each organism has.

Regulatory elements in cis are non-coding regions of DNA that are capable of regulating the transcription of nearby genes.

DNA methylation is a process whose objective is to add methyl groups to the DNA molecule in the cell, in this process a change in the activity of a segment of DNA can occur without this meaning changing the sequence.

The sequence of DNA methylation sites occurs within the genome of an organism
