Explanation:
Detailed explanation-1: -For example, proline is represented by four different codons (CCU, CCC, CCA, and CCG).
Detailed explanation-2: -The enzyme that converts DNA into mRNA is called RNA polymerase, which attaches to the DNA double helix as shown here. Once attached, RNA polymerase can unwind the helix and begin copying one of the DNA strands to form an mRNA transcript of the gene.
Detailed explanation-3: -The codon CGA on mRNA sequence codes for amino acid cysteine, tRNA corresponding to this codon is UCU anticodon.
