Which of the following if added to this sequence a—g—a—t—g—c—g—a—g—t—t—a—c—g—g might create an insertion mutation? a. a dna molecule b. a fat molecule c. a sugar molecule d. an a, g, t, or c

D. Adding another base pair will re-arrange your DNA sequences and cause an insertion mutation. This will make your codons group of differently, and possibly give you a BAD mutation. However, sometimes the codons still make the same proteins as its supposed to, the mutation will NOT affect you.

Example:

THE BIG FAT CAT ATE THE RAT

Now, if i were to add a letter (X) to this and make the letters group up in three aka the codons:

THE XBI GFA TCA TAT ETH ERA T

As you can you can see, adding a base pair in a DNA insertion will usually have a negative effect, specifically a insertion mutation.

This is a time line from 685 to 978

Awell breed cat that has no defects or has never been damaged before.hope this ! mark me as brainiest!
