Which best describes the process of insertion?
a. occurs when part of a chromosome breaks off and is inserted into the middle of another chromosome
b. occurs when part of a chromosome breaks off and reattaches backward on the same chromosome
c. occurs when part of a chromosome breaks off and does not reattach
d. occurs when part of a chromosome breaks off and attaches to another chromosome

Answer;

D. occurs when part of a chromosome breaks off and attaches to another chromosome

Explanation;

-An insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence.

-An insertion mutation is a permanent change in a DNA sequence caused by the addition of nucleotides. If the number of nucleotides inserted is a multiple of three, then it is a non-frameshift mutation.

The correct answer is option A. "occurs when part of a chromosome breaks off and is inserted into the middle of another chromosome".

Explanation:

Chromosome insertion refers to a mutation that occurs when part of a chromosome breaks off and is inserted into the middle of another chromosome. This dramatic changes involve the random insertion of large DNA fragments that most of the time carry one or more functional genes. Sometimes this mutation can cause the silencing of genes in the chromosome where the fragment was inserted due to disruption in its reading frame sequence.
