MATERNAL MRNA Meaning and
Definition
-
Maternal mRNA refers to the messenger RNA molecules that are synthesized within the oocyte or egg cell of female organisms. mRNA is a crucial molecule in gene expression, as it carries the genetic information from DNA to the ribosomes, where it is later translated into proteins. Maternal mRNA, specifically, refers to the RNA molecules that are present in the egg cell before fertilization occurs.
During oogenesis, the process of egg cell development, the oocyte accumulates a pool of mRNA molecules necessary for early embryonic development. This maternal mRNA is produced and stored within the egg cell, serving as a critical resource for the developing embryo. Unlike most other cells in the organism, eggs contain a unique set of mRNA molecules that are specific to their development.
Once fertilization takes place, the zygote, which is the resulting cell from the fusion of the egg and sperm, starts its developmental journey. The zygote starts to utilize the maternal mRNA pool present in the cytoplasm to initiate protein synthesis, as the zygote's own genome is not actively transcribed at this early stage. The maternal mRNA provides the essential building blocks for various cellular processes, such as cell division, differentiation, and the formation of organs and tissues during early embryonic development.
However, as the embryo continues to develop, the maternal mRNA molecules gradually degrade and lose their functionality. This degradation allows the embryo's own genome to take over and start transcription and translation, ensuring the synthesis of proteins specific to its own development.
In summary, maternal mRNA refers to the RNA molecules stored in the egg cell prior to fertilization, providing a vital source of genetic information for early embryonic development before the zygote's genome becomes active.

Etymology of MATERNAL MRNA
The word "maternal" comes from the Latin word "mater" meaning "mother". It is commonly used to refer to anything related to or characteristic of a mother.
The acronym mRNA stands for "messenger RNA". RNA, or ribonucleic acid, is a molecule involved in various cellular processes, including protein synthesis. Messenger RNA is the type of RNA that carries genetic information from the DNA to the ribosomes in the cytoplasm, where it is used as a template for protein synthesis.
Therefore, the term "maternal mRNA" refers to the messenger RNA molecules that are present in an organism's cells and are specifically inherited from the mother. These mRNA molecules carry genetic information that is derived from the mother's DNA and are involved in various biological processes during development.
