Question

question 23 2.5 points what is an example of a mutation in an allele? a a base change in the gene coding sequence b a base change in the genes regulatory regions c a deletion of a base within the gene d an insertion of a base within the gene e all of the above. question 24 2.5 points why do they use viruses as vectors to transfer dna into cells? a because viruses are small b because viruses kill the cells c because viruses normally insert dna into cells d because viruses only infect plants e because viruses do not contain dna

Explanation:

For Question 23, a mutation in an allele can be caused by a base - change in the gene coding sequence, regulatory regions, base deletion, or base insertion within the gene. For Question 24, viruses are used as vectors to transfer DNA into cells because they have a natural ability to insert their genetic material (DNA or RNA) into host cells.

Answer:

Question 23: E. All of the above
Question 24: C. because viruses normally insert DNA into cells
