Question

PLEASE help fast! WILL GIVE MEDAL.
One difference between a point mutation and a chromosomal mutation is that ___.

A.) a point mutation affects the DNA of more genes than a chromosomal mutation
B.) a point mutation can involve an insertion or deletion, but cannot result in frameshift.
C.) a chromosomal mutation can change the number of chromosomes in a cell.
D.) a chromosomal mutation is more likely to be passed on to offspring or daughter cells.

Answer 1

B is false. Insertions and deletions cause frameshifts. We can cross that out.

Answer 2

ok sounds good

Answer 3

A is false. A point mutation only affects a few genetic sequences whereas a chromosomal mutation can affect a wide range of genes. So we can also cross that out.

Answer 4

alright

Answer 5

D is not a good answer. All types of mutation have about the same probability of being passed on through heredity.

C is the best answer. Chromosomal mutations can alter the number of chromosomes a disorder known as aneuploidy.

Answer 6

ok, thank you so much(:

Answer 7

You're welcome

Answer 8

To be specific, B can be false. It just depends on how many insertions or deletions occur.

Answer 9

C was correct!(:
