What 3' to 5' DNA sequence would correspond to a 5'-AUG-3' start codon?

To determine the complementary DNA sequence, you need to remember the base pairing rules: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). To find the complementary sequence, you reverse the direction and substitute the corresponding bases:

The 5'-AUG-3' start codon has the corresponding 3'-TAC-5' sequence.
The complementary 3' to 5' DNA sequence would be 5'-TAC-3'.

To determine the DNA sequence corresponding to a given mRNA sequence, you need to use the rules of base pairing in DNA.

For protein synthesis, the mRNA sequence is read in a 5' to 3' direction. Therefore, to determine the DNA sequence, you need to find the complementary sequence by replacing each base with its complementary base: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).

The 5'-AUG-3' sequence represents the start codon, which initiates protein synthesis. So, to find the corresponding DNA sequence:

1. Replace each base of the RNA sequence with its complementary base in DNA: A with T, U with A, and G with C.

Therefore, the DNA sequence corresponding to the 5'-AUG-3' mRNA start codon is 3'-TAC-5'.
