...Activation Embryonic stem cells are valuable and special, which are isolated from early embryonic stages and forms the system for the development of the embryo. Embryo gene activation is the process in which an embryo starts transcription of the new genome. For synthesis of proteins and cleavage, embryo gene activation is of great importance as it aids in those processes. The period in which embryos take to break and start the embryonic gene activation is different and depends on the species of the animal (Haian 15). Embryonic genes, which are active prior to the 4-cell stage, are small in number and they code for proteins used in controlling and stabilizing maternal mRNA and proteins... Embryo Gene...

Since then, there has been an explosive quantity of research on the enzyme, with its knowledge database growing day by day. NOS are dimeric enzymes that catalyse the chemical reaction using the substrates l-arginine, NADPH, and oxygen to give the products of nitric oxide (NO), citrulline and NADP. They are associated with various cofactors, including tetrahydrobiopterin, FAD, FMN and iron protoporphyrin IX. Although there has been... ? ‘Your Human Anatomy 3 Dec Pathways of NOS...
