The ‘Central Dogma of Molecular Biology’ enunciated by Francis Crick in 1958 answeres the question about the complex structure and the mode of function of the body of animals. A cell, the smallest unit of the body, is composed of ‘proteins’ like a precise machine to form the functional basis of life. The ‘Central Dogma’ describes the series of steps involved in producing ‘function specific’ protein from DNA (a nucleic acid occurs in the cell chromosome) where all the informations about life remain coded. In the first step, the replicating DNA is copied or transcribed as mRNA (messenger RNA) in the cell nucleus with the help of an enzyme called RNA polymerase.The transcribed and processed mRNA then moves from nucleus to the ribosome of cytoplasm where it is decoded or translated into amino acids with the help of tRNA (transfer RNA).The newly formed amino acids are linked together by the aid of various enzymes to form protein for performing specific function exactly in a way it was blueprinted in the source DNA.

Hello there!
BeantwoordenVerwijderenI found this piece of text quite interesting to read. It was pleasant to have molecular biology freshened up; in the past I've had classes on this field but most of it had faded. In that case I’m thankful for my education, it helped me understand the ‘Central Dogma’. However, I can imagine that for non-scientists the use of terms as "nucleic acid", "enzyme" or "ribosome" may be discouraging. Also, I was wondering if the processes of coding, replication, and transcription could be mentioned to your friends without fully explaining them. I’ve spotted some tiny mistakes but that didn’t subtract from the sheer joy of reading. Using the shortened 'Central Dogma' in the third sentence nicely added to the flow of the text. I also couldn't help but notice you used the exact same picture as the wikipedia article about this subject – don’t worry, it was a nice, structured chart and it helped. Linking to Francis Crick was a great idea, I clicked on it straight away to be honest.
Thanks for the read,
