Question 12
after many cell divisions, a segment of dna has more base pairs than it originally did. explain what has happened.
can you me with this, that'd be great! !

The correct answer is insertion mutation.

The mutation is defined as the change in the DNA (deoxyribonucleic acid) sequences. The insertion mutation is a type of mutation, in which the insertion of the nucleotides takes place in the DNA sequences, resulting in an increase in the total number of base pairs in the DNA sequence. So, the insertion mutation has resulted in the increase in the base pairs in this case.  

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
