Answer: 1 the complete set of sequences that Xist interacts with in an organism
Step-by-step 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
