NUCLEOSYNTHESIS / NUCLEOEDITING
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons. The first nuclei were formed about three minutes after the Big Bang, through the process called Big Bang nucleosynthesis. It was then that hydrogen and helium formed to become the content of the first stars, and this primeval process is responsible for the present hydrogen/helium ratio of the cosmos. With the formation of stars, heavier nuclei were created from hydrogen and helium by stellar nucleosynthesis, a process that continues today. Some of these elements, particularly those lighter than iron, continue to be delivered to the interstellar medium when low mass stars eject their outer envelope before they collapse to form white dwarfs. The remains of their ejected mass form the planetary nebulae observable throughout our galaxy.
It is an accepted fact that DNA directs to produce RNAs and RNAs execute their functions for what they have been produced, ‘what you have & what U get’, whatever it can be. Here the master and the executive are complementary to each other in most of the cases. This is a general rule, but in certain exceptions, the mRNA produced; a copy of the master, for a functional protein, is different from what is required. In this context the mRNA transcribed cannot be translated to a product that is required and desired by specific cell type. Many such genes are transcribed with certain sequences missing or sequences not required or some sequence in excess, so they have to be substituted, removed or modified. But in many cases the same mRNA produced by the same gene in different tissue types is modified by single bases of a specific nucleotide to the needs of the cell types.
