Protein synthesis involves two stages, named as transcription and translation. During transcription, information present in DNA molecule is used to make mRNA molecule, while translation involves formation of polypeptide chain or protein by using information present in mRNA in the form of codons.
Prokaryotic organisms lake true nuclei, hence in these organisms both transcription and translation take place in cytosol. In eukaryotic organisms, transcription takes place in nucleus, while translation takes place in ribosomes, present in the cytosol.
Codon is a set of DNA or RNA nucleotides so each amino acids are coded by 3 bases. For the specification of 4 amino acids, 12 bases are required. 3*4=12
<span>Answer:
100 amino acids.
Each amino acid corresponds to a codon of 3 nucleotides. Therefore, a coding region of 300 nucleotides contains 100 codons and will produce a polypeptide of 100 amino acids in length.</span>
