Thus, the biological process through which protein is synthesized is called translation. Initiation. The DNA replication in prokaryotes takes place in the following place: The two strands of DNA unwind at the origin of replication. The first step is the reaction of an amino acid and ATP to form an aminoacyl-adenylate (also known as aminoacyl-AMP). It uses single-strand DNA to synthesize a complementary RNA strand. As with mRNA synthesis, protein synthesis can be divided into three phases: initiation, elongation, and termination. It occurs in two stages: transcription and translation. Transcription in prokaryotes is one important step related to both DNA, RNA, and mRNA formation. Ab ract. In the second step, without leaving the enzyme, the aminoacyl group of aminoacyl-AMP is transferred to the 3’ end of the tRNA molecule to form aminoacyl-tRNA.

It is based on the presumption that a source text can have different translations and examines the factors underlying those differences which tend to be external factors associated with the socio-cultural environment in which the translation process is embedded. The different types of RNA are involved in various cellular process. All the 20 aminoacids are activated and bound to 3’ end of their specific tRNA in the presence of ATP and Mg++. Most often the starting amino acid is methionine in eukaryotes and N-formyl methionine in prokaryotes. The activation of aminoacids is catalyzed by their aminoacyl tRNA synthetases. Translation is the process through which proteins are synthesized. This process helps in the growth and repair of damaged cells. This process is called charging of tRNA or amino-acylation of tRNA.
