Question

Quizplus · Accepted Answer

Erasure and re-establishment of imprinting marks typically do not occur in somatic cells. Imprinting marks are mainly erased and re-established in germ cells (sperm and oocytes) during gametogenesis, ensuring proper gene expression in the offspring. Somatic cells, which make up the majority of the body's tissues and organs, maintain their imprinting marks throughout the life of the organism.
