Chapter 21: Problem 105

Part of a certain DNA sequence is G-G-T-C-T-A-T-A-C. What is the complementary sequence?

Short Answer

Expert verified
The complementary DNA sequence is C-C-A-G-A-T-A-T-G.

Step by step solution

01

Identify the given DNA sequence

The DNA sequence given is: G-G-T-C-T-A-T-A-C
02

Apply the base-pairing rules

Replace each base in the sequence with its complementary base using the base-pairing rules: A pairs with T, and C pairs with G.
03

Create the complementary sequence

Replace each base in the given sequence with its complementary base: G -> C (G pairs with C) G -> C (G pairs with C) T -> A (T pairs with A) C -> G (C pairs with G) T -> A (T pairs with A) A -> T (A pairs with T) T -> A (T pairs with A) A -> T (A pairs with T) C -> G (C pairs with G)
04

Combine the complementary sequence

Combine the complementary bases to form the complementary sequence: C-C-A-G-A-T-A-T-G The complementary DNA sequence is C-C-A-G-A-T-A-T-G.
