Discuss the Three Steps in Protein Synthesis

Question

Examlex · Accepted Answer

The Answer is 1. Uncoiling of DNA-the DNA segment or gene that specifies one polypeptide or protein uncoils.
2. Transcription (DNA-directed synthesis of mRNA)-one strand of DNA acts as a template for the synthesis of the complementary mRNA molecule, and there is a transfer of information from the DNA's base sequence (cod.Einto the complementary base sequence of mRNA (codon).
3. Translation (RNA-directed synthesis of a polypeptide or protein) involves five steps. First, mRNA leaves the nucleus and attaches to ribosomes. Second, tRNA (anticodon) transports an amino acid to the mRNA strand and recognizes a mRNA molecule (codon). Third, the codon and the anticodon bind. Fourth, the ribosome moves the mRNA strand along as each codon is read sequentially. Finally, as each amino acid is bound to the next by a polypeptide bond, its tRNA is released. The polypeptide or protein chain is released when the termination (stop) codon is read.
