Question

which of the following amino acids is coded for by using the following dna sequence: tga
○ threonine (thr)
○ proline (pro)
○ serine (s)
○ valine (v)

Explanation:

Step1: Convert DNA to mRNA

DNA sequence: 3'-TGA-5' → mRNA (complementary, 5' to 3'): 5'-ACU-3'

Step2: Match mRNA to amino acid

Use the codon wheel: ACU corresponds to Threonine (Thr)

Answer:

Threonine (Thr)
