Considering the mRNA sequence of the insecticide-resistant fruit flies, the corresponding sequence of nucleotides on the individual's DNA is: - AGA - VCE - SSCE Biology - Question 22 - 2014 - Paper 1

To find the corresponding DNA sequence, we must convert the mRNA codons to their DNA counterparts. The base pairing is as follows:

• Adenine (A) pairs with Thymine (T)
• Uracil (U) pairs with Adenine (A)
• Cytosine (C) pairs with Guanine (G)
• Guanine (G) pairs with Cytosine (C)

Using this template:

• For AGA in mRNA, the corresponding DNA codon is TCT.
• For AUA in mRNA, the corresponding DNA codon is TAT.
• For CGA in mRNA, the corresponding DNA codon is GCT.
• For TGT in mRNA, the corresponding DNA codon is ACA.

Combining these, the sequence of nucleotides on the individual's DNA corresponding to the mRNA is:

• TCT, TAT, GCT, ACA.
