Asked by Sam
What would be the result of a cytosine base being substituted for a thymine base in a DNA segment during DNA replication?
*
1 point
The cytosine base would pair with adenine when the DNA was replicated.
The sequence could code for the wrong amino acid during translation.
There would be no effect on the DNA.
The entire segment of DNA would be affected.

The sequence could code for the wrong amino acid during translation.
(Replacing a T with a C is a point mutation; it changes a single codon and may cause a missense mutation — though it could also be silent depending on the codon. C pairs with G, not A, and the whole segment wouldn't necessarily be affected.)
