Question
The imprints are made up of ____________ groups.
Phenyl
Methyl
Ethyl
Hydroxyl
Phenyl
Methyl
Ethyl
Hydroxyl
Hint:
Methyl
The correct answer is: Methyl
In genes that undergo genomic imprinting, the parent of origin is often marked, or “stamped,” on the gene during the formation of egg and sperm cells. This stamping process, called methylation, is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA.
