Detailed explanation-1: -The Central Dogma of Molecular Biology states that DNA makes RNA makes proteins (Figure 1). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
Detailed explanation-2: -During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.
Detailed explanation-3: -Rather, the translation of mRNA into protein depends on adaptor molecules that can recognize and bind both to the codon and, at another site on their surface, to the amino acid. These adaptors consist of a set of small RNA molecules known as transfer RNAs (tRNAs), each about 80 nucleotides in length.
Detailed explanation-4: -The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.
