MATERNAL MESSENGER RNA Meaning and
Definition
-
Maternal messenger RNA (mRNA), also known as maternal transcript, refers to the type of RNA molecule that is derived from the mother and present in the developing oocyte or egg cell in organisms. mRNA is a key player in the process of gene expression, carrying the genetic information from the DNA to the ribosomes where proteins are synthesized.
In the case of maternal mRNA, it is formed in the mother's cells and subsequently transported into the egg cell during oogenesis, the process of egg cell formation. Maternal mRNA provides a critical role in early embryonic development prior to the activation of the embryonic genome, influencing various processes such as cell division, differentiation, and cell fate determination.
Maternal mRNA is crucial in transmitting important developmental instructions from the mother to the developing embryo, as it contains information inherited from the maternal genome. This mRNA is actively synthesized in the mother's cells and selectively stored in the egg during oogenesis, allowing it to be available and functional during the early stages of embryonic development.
However, as the embryo develops and the zygotic genome becomes active, the maternal mRNA gradually degrades and is replaced by zygotic mRNA, which is transcribed from the embryo's own genetic material. This transition ensures that the embryo relies on its own genetic instructions rather than those provided by the mother.
