Monserrat Keller · Answer 1

The above statement is false.

Explanation:

As we can infer from the question, Thymine is being replaced by Cytosine at position 3 of a genetic sequence. This means that only a single change is being made in the genetic sequence. This change will cause a faulty protein to be formed. The faulty protein will be associated with this genetic sequence.

Hence, not all of the changes existing between the cichlid and coelacanth/frog will be associated with this single base change.

However, instead of replacement of C with T, if an addition or deletion of a base might have occurred, then the entire genetic sequence would have been altered causing many changes.
