Question

Which are possible outcomes of a mutation in a gene that codes for a transcription factor?

The ability of the transcription factor to bind to DNA may be destroyed.
The ability of the transcription factor to bind to DNA may be reduced.
The ability of the transcription factor to bind to DNA may be unchanged. Any of the above is possible.

Answer 1

Any of the above is possible because anything can happen to a gene when it is transcripted. Mutation happens when there is a defect of coding the right genes resulting to a change of DNA sequence. DNA may be reduced or unchangeable by a transcription factor because of mutation in a gene.
