What is/are the amino acid products when we have an mRNA that is AUGAAAUUU?
To determine the amino acid sequence encoded by an mRNA sequence, we first need to transcribe the mRNA into its complementary DNA sequence. For this, we replace each occurrence of uracil (U) with thymine (T).
So, the complementary DNA sequence of AUGAAAUUU would be ATGAAATTT.
Next, we need to divide this DNA sequence into codons. Codons are groups of three nucleotides that code for a specific amino acid. In this case, each codon will represent an amino acid product.
The codons in the DNA sequence ATGAAATTT are:
- ATG
- AAA
- UUU
Now, we need to refer to the genetic code, which determines the amino acids encoded by each codon. AUG is a special codon called the start codon, which codes for the amino acid methionine (Met). AAA codes for the amino acid lysine (Lys), and UUU codes for the amino acid phenylalanine (Phe).
Therefore, the amino acid products of the mRNA sequence AUGAAAUUU are methionine (Met), lysine (Lys), and phenylalanine (Phe).
