Question

Select the correct match from the following.

Options

• Histone proteins - Leucine and serine

• Stop codons - UUL, UUC, UUC

• Codon CUC, UCU - Arginine and Lysine

• Phenylalanine - UUU

Answer 1

Phenylalanine - UUU

Explanation:

• The right match combination is phenylalanine - UUU.
• The codons UUU and UUC only encode phenylalanine. Because Histone proteins are made up of two positively charged amino acids, lysine and arginine, rest pairs can be corrected.
• Stop codons such as UAG, UAA, and UGA play an important function in signalling the end of a protein coding sequence.
• CGU, CGA, and CGC are the codes for arginine. Lysine is denoted by the letters AAA, AAG.
