Which base sequence correctly completes DNA Strand 2?
Understand the Problem
The question is asking which base sequence correctly completes the DNA sequence provided. This involves understanding DNA pairing rules, where adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C).
Answer
3'-C-G-C-A-T-G-5'
The final answer is C: 3'-C-G-C-A-T-G-5'.
Answer for screen readers
The final answer is C: 3'-C-G-C-A-T-G-5'.
More Information
DNA strands are complementary, resulting in specific base pairs that match together through hydrogen bonds. For the sequence '3'-G-C-G-T-A-C-5', the complementary sequence is '5'-C-G-C-A-T-G-3'.
Tips
A common mistake is forgetting the DNA strand orientation, leading to confusion in pairing. Always ensure you convert 3' to 5' or vice versa correctly.
