The process of protein synthesis can be divided into two parts. The first part is transcription, which produces a molecule of messenger RNA (mRNA) from the gene. Transcription takes place in the nucleus of the cell.

Web3 de jan. de 2024 · A. The (Nearly) Universal, Degenerate Genetic Code. The genetic code is the information for linking amino acids into polypeptides in an order based on the base sequence of 3-base code words (codons) in a gene and its messenger RNA (mRNA).With a few exceptions (some prokaryotes, mitochondria, chloroplasts), the genetic code is … WebSo, it is clear that a gene with 600 nucleotides will have 600 nitrogenous bases and it is known that 3 nitrogenous bases form a single codon. Therefore, 600 nucleotides will have 600/3 = 200 codons. Now, one codon can code for a single amino acid, so 200 will code for 200 amino acids. Hence, option 1 is correct. Download Solution PDF.
