Protein Synthesis And Importance Of Essential Amino Acids As Well As Energy Sources To understand the process of protein synthesis we need to concentrate over central dogma of molecular biology. According to which, DNA replicates and gives rise to another DNA molecule, then, RNA is generated through transcription and further translation occurs, in which proteins are synthesized. For instance, One DNA base sequence is as following T A C T T A C C G A G A T T C T T G T T T A T C Due to complimentarity phenomenon (if A is present in DNA then, in m-RNA sequence U would appear, while in case of presence of C, G would appear in m-RNA and vice-versa) the sequence of m-RNA would be as follows A U G A A U G G C U C U A A G A A C A A A UAG and it would be synthesized with the help of DNA dependent RNA polymerase and other transcriptional factors as sigma etc. Now, proteins sequence depends on the base sequence of m-RNA which works as a middle man between DNA and proteins. Here, we need to take three nucleotide bases together
