Accurate Protein Synthesis: Five Mechanisms

Protein synthesis is a vital biological process that involves the accurate transcription and translation of genetic information. To ensure that the final product is a correctly sequenced protein, a number of mechanisms can be used. Here, we will explore five mechanisms that ensure accuracy in protein synthesis. The first way to ensure accuracy is through the use of enzymes that specifically recognize the correct sequence of codons, or triplets of nucleotide bases, in each gene and read it accurately during the process of transcription. These enzymes can recognize the correct substitution of one codon for another and so prevent errors from occurring (Haran et al., 2017). The second mechanism is the presence of proofreading enzymes, which recognize and repair any mistakes which occurred during transcription. These enzymes, such as exonucleases, recognize incorrect nucleotides, remove them and replace them with the correct ones (Pereira et al., 2016). The third approach is the use of RNA polymerases which contain proofreading domains. These domains recognize any errors which occur during transcription and stop the process until the. Cont…
