Question

3. Human (Homo Sapiens)
Given Strand: T C T G A G T T C
Complementary Strand: ______________________
Part of the OCA2 gene sequence. The OCA2 gene codes for a protein
involved in pigmentation and variation in its sequence is a major influence
on whether we have brown or blue eye color.

Answer 1

To find the complementary strand of the given DNA sequence, you simply pair each nucleotide with its complementary base:

- A (adenine) pairs with T (thymine)
- T (thymine) pairs with A (adenine)
- C (cytosine) pairs with G (guanine)
- G (guanine) pairs with C (cytosine)

Given Strand: T C T G A G T T C
Complementary Strand: A G A C T C A A G

So, the complementary strand is:

**A G A C T C A A G**
