How many differences are seen between the non-mutated DNA and the mutated DNA? (Hint: how many nitrogen bases are different between the two DNA sequences?)
Understand the Problem
The question is asking to compare the DNA sequences of normal and mutated hemoglobin to determine the number of differences in nitrogen bases. Specifically, it requires identifying how many bases are different between the two sequences.
Answer
1
The final answer is 1.
Answer for screen readers
The final answer is 1.
More Information
The difference between the two DNA sequences is in the sixth nitrogen base, where a T in the normal sequence is replaced by an A in the mutated sequence.
Tips
A common mistake is not comparing each position in the sequences carefully, leading to errors in counting base differences.
