Since your school days, you may have read about DNA and RNA without understanding the impact of both DNA and RNA in-depth there. However, RNA stands for ribonucleic acid. It is a linear polymer of nucleotides that is predominantly found in the cytoplasm of a cell and it is associated with microsomes. Interestingly, microsome is a tiny granule that exists in the cytoplasm and it is responsible for protein synthesis. But, you should know here that RNA works like a messenger with a view to passing genetic information from DNA (deoxyribonucleic acid) to the cells of a body. It further connotes that the human total RNA count is important with a view to detecting the presence of the rogue elements such as the virus in the body. In other words, RNA has all that it takes to regulate, express, code, and decode in the human body.
What RNA does:
They say knowledge is power to you. You must, therefore, know what RNA does in a human body in the first place that, in turn, will help you stand out in life. For instance, whether you will be able to pursue your dream of becoming a soccer player. Here is a list of points to ponder on the periphery and scope of work for RNA.
- Biological reaction: Since the time of fetus, biological reactions keep taking place within the human body. However, at the age of a fetus, biological reactions of it is influenced by that of the mother. After birth, it is the baby’s RNA that controls the biological reactions. For instance, the RNA starts catalyzing biological reactions here and at the time, it keeps the channels of communication open with the cellular signals. It is also known to control gene expressions.
- Protein synthesis: Protein synthesis is perhaps the most demanding task of RNA where the molecules of RNA in a human body direct the accumulation of proteins on the ribosome.
- Supply of amino acid: At the time of protein synthesis, tRNA (transfer RNA) delivers amino acids to ribosomes. Then, the amino acids are bonded together and give birth to protein. Interestingly, proteins keep the signal system alive between the cells.
- Disease control: Since RNA proteins play an important role in the wellbeing and care of the organisms, RNA also helps to control diseases.
RNA can be damaged as well due to external factors such as the ultraviolet light, nitration, and oxidation. An oxidative damage to RNA results in human neurodegenerative disorders. Alzheimer’s disease, for instance, is an acute case of neurodegenerative disorders. The research around the world has proved that damages through oxidation are normal in the case of RNA. But, the close proximity to mitochondria truly causes more damage to RNA. However, RNA is susceptible to oxidative damages and thus, it may be affected during the coding and noncoding period.
Therefore, the human total RNA has a greater role to play in the growth and development of the human body on one hand and on the other, it has been instrumental in the regulation of the molecular processes that are critical to the homeostasis.
