What occurs during frameshift mutation?

yuradex [85]

Answer:

C) An extra chromosome is added, causing mismatching of the chromosome pairs.

Explanation:

Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.

According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.

In frameshift mutation, the insertion or deletion causes the

normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.

Which diagnostic test is used for the direct visualization of ligaments, menisci, and articular surfaces of joints?

Sati [7]

Arthroscopy is done for direct visualization of the ligaments, menisci, and articular surfaces of the joints. Thus, option A is correct.

<h3>What is the role of ligament?</h3>

Ligaments are type of connective tissue which help to connect bones, joints and organs. It provide support internal parts of the body.

It is made of a band of connective tissue, collagenous fibre and spindle-shaped fibrocytes which is an elastic fibers.

Ligaments holds bones together, stabilize it, provide strength to joints etc.

By the use of Arthroscopy doctors can diagnose and treat the joint’s structural problems like any dysfunction. Hence, Option A is correct.
