Chapter 28: Problem 33

Write the mRNA codons for the following. (a) Valine (b) Histidine (c) Glycine

Short Answer

Expert verified
Answer: (a) The mRNA codons for Valine are GUU, GUC, GUG, and GUA. (b) The mRNA codons for Hisitidine are CAU and CAC. (c) The mRNA codons for Glycine are GGU, GGC, GGA, and GGG.

Step by step solution

01

(a) Valine codons

To find out the mRNA codons for Valine, we can refer to a codon table. Valine has four mRNA codons, which are GUU, GUC, GUG, and GUA.
02

(b) Histidine codons

To find out the mRNA codons for Histidine, we will again refer to a codon table. Histidine has two mRNA codons, which are CAU and CAC.
03

(c) Glycine codons

Lastly, to find out the mRNA codons for Glycine, we will refer to the codon table one more time. Glycine has four mRNA codons, which are GGU, GGC, GGA, and GGG.
