Question

write the amino acid using its three - letter abbreviation. write stop for a stop codon.
dna sequence aaa
mrna codon
amino acid

Explanation:

Step1: Find mRNA codon

DNA sequence is AAA. In transcription, adenine (A) in DNA pairs with uracil (U) in mRNA. So the mRNA codon is UUU.

Step2: Find amino acid

Using the genetic code, the codon UUU codes for the amino acid Phenylalanine (Phe).

Answer:

mRNA codon: UUU; amino acid: Phe
