Question

An inversion occurs along part of a chromosome. How does the inversion most likely affect the region in which it occurs?

A. Recessive alleles in the region become dominant alleles.

B. The coding sequence in the region disappears entirely from the cell.

C. Multiple frame-shift errors in the region are triggered after translation.

D. The information in the region is read differently during transcription.

Answer 1

I think the answer is A Because i remember taking this test and yea...thats my answer 20/10

Answer 2

Answer: The correct answer is-

D. The information in the region is read differently during transcription.

Inversion is a type of mutation ( that is permanent change in the genetic material of living organism) that occurs after break in a chromosome, which is followed by the rearrangement of the broken segment.

In other words, when a segment of chromosome is broken and reversed/rearranged within itself, it is called inversion.

It leads to change in the DNA sequence, due to which information in the region ( that is genetic information present in the form of nucleotide sequences) is read differently during transcription ( conversion of DNA to mRNA).

Thus, option D) is the right answer.
