Question

What is genomic imprinting? O the transmission of a gene from only one of the parents, either the male or the female O inactivation of an important gene that is crucial for the cell to survive by environmental factors the inactivation of one of the X chromosomes in female mammals, leaving only one active O X chromosome O the methylation of cpG islands to produce 5-methylcytosine, which inactivates the gene o the differential expression of an allele depending on whether it is inherited from the male or female parent

Explanation / Answer

Genomic imprinting is the inactivation of one x chromosome in female mammal leaving only one active chromosome.

Paramutation is an interaction between two genes at different loci that leads to a heritable change in one of the alleles.

Epigenome is the sequence of DNA methylation sites within the genome of an organism. Last option is correct.

Acetyaltion is related the increased transcription

because acetylation reduce the affinity of the hisone for DNA and possible also reduces the interaction between individual that lead the formation of 30nm chromatin fiber. The acetylated histone forming euchromatin structure.
