Ans 21-) GGGGCUCUC is the correct option.
as the mRNA codon GGG encodes for glycine. mRNA codon GCU encodes for alanine. MRNA codon CUC codes for leucine.
Ans 22-) Ribosomes is the correct option.
Ribosome is generally, a ribonucleoprotein which is formed from the complex of protein and RNA. Ribosome has two subunits. Ribosomal smaller subunit will bind to mRNA while the larger subunit will bind to the aminoacyl tRNA

3. A small peptide has the amino acid sequence Phe-Leu-Tyr-Ala-Leu-Gly-Glu. A shorter variant of this peptide was discovered that had the sequence Phe-Leu-Tyr-Ala; it was demonstrated that this shorter peptide was due to a single base substitution in the second Leu codon. What type of mutation (missense, nonsense, frameshift) gave rise to this shorter peptide? Which of the six possible Leu codons was used in the synthesis of the original (long) peptide (can you eliminate some as possibilities)?
