21. Option A is correct. During RNA processing a guanosine cap is placed at the 5' end of the mRNA.
24. Option b is correct. The genetic code is a triplet code.
26. Option B is correct. The first amino acid arrives with it's tRNA at the P site during initiation of translation.
29. Option a is correct. The second and all subsequent amino acids arrive with their tRNAs at the A site during elongation phase of translation.
