Write all the possible codon sequences for alanine.
i. What amino acid is encoded by the codon AGC?
ii. List all the other codons that can code for the amino acid in (i).
What amino acid is encoded by the codon UAU?
Predict which amino acid(s) would have the least codon that is needed in protein synthesis (translation).
A certain protein involved in muscle contraction, myosin, is composed of 196 amino acids. Assuming each amino acid is coded by a unique codon and there are no introns in the gene coding for myosin, how many heterocyclic bases must be present in the informational DNA strand to code for this protein?
Look at the following table to determine the codons for amino acid glycine.
Which of the following sets of codons code for the amino acid valine?
Select the correct set of codons corresponding to the amino acid serine.
A researcher is studying a peptide known as β-endorphin, which plays a role in pain and pleasure. What is the amino acid sequence of the β-endorphin peptide from the given mRNA sequence below?
AUG AAU CCG GGU AGA UGA
A study was conducted on the peptide α-melanocyte-stimulating hormone (α-MSH), which plays a role in appetite suppression. Determine the amino acid sequence of the α-MSH from the following mRNA strand:
AUG UCU ACC UGG UAA
