Question

I only have two questions, thank you! One difference between a point mutation and a chromosomal mutation is that ____

Answer 1

For the first question the answer would be B. 
For the second question the answer would be D. I am not 100% on this but its my best guess. 

Answer 2

Answer:

1. The most appropriate answer would be an option C.  

A point mutation refers to the mutation or change that occurs at only one or a few nucleotides of the DNA.

Usually, a single nucleotide is substituted with the wrong nucleotide due to which only a single codon is affected.

However, it can cause frame shift mutation if insertion or deletion of nucleotide takes place.

In contrast, in chromosomal mutation long segment of DNA is involved. It may involve one or more genes. It mainly includes insertion, deletion, translocation, and inversion.

In addition, chromosomal mutation can cause change in the number or sets of chromosomes such as poliploidy, aneoploidy et cetera

2. The correct answer would be C. A point mutation

A point mutation refers to the mutation or change that occurs at only one or a few nucleotides of the DNA.
