Mutations in what class of genes have probably been responsible for many of the changes leading to the great diversity of life existing today? genes that regulate mitosis genes for aerobic respiration dna repair genes developmental genes genes for digestive enzymes

Yes but cells also help get life to where it is right now and cells will also be changing genes connect with who we are and what we are and without those genes and cells we wouldn't be who we are today. genes do regulate mitosis but not for aerobic respiration genes give use our characteristics like girl,boy. DNA does help repair genes like per say you got a scrape on your leg or arm the DNA would clot so that the bleeding would stop and that would cause it to scab over.

The answer is b. hope this !
