Question

What results from the exchange of DNA segments between nonhomologous chromosomes?

A) Point mutation
B) Translocation mutation
C) Insertion mutation
D) Deletion mutation

Answer 1

A translocation mutation occurs when a segment of a chromosome dissociates and reattaches to a different, nonhomologous chromosome. This can result in the rearrangement of genes and regulatory sequences.

Step-by-step explanation:

A translocation occurs when a segment of a chromosome dissociates and reattaches to a different, nonhomologous chromosome. This exchange of DNA segments between nonhomologous chromosomes is called a translocation mutation. It can result in the rearrangement of genes and regulatory sequences, which can have both benign and devastating effects depending on the specific alterations.
