Mutations Foldable Quiz

Where do chromosomal mutations occur?

• Within a single nucleotide base

• On a large scale including a large segment of DNA

• Outside the DNA structure

• Within the histones

What do gene mutations affect?

What is the structure that DNA wraps around to form a nucleosome?

• Chromosome

• Nucleotide

• Histone

• Gene

What is a deletion in the context of chromosomal mutations?

• The duplication of a segment of the chromosome during replication.

• The rearrangement of the genetic material within the chromosome.

• The loss of a segment of the chromosome during replication.

• The addition of a new segment to the chromosome.

What occurs during a chromosomal duplication mutation?

• A segment of the chromosome is removed.

• A segment of the chromosome is repeated during replication.

• The entire chromosome is replicated.

• The chromosome structure is inverted.

What is a chromosomal inversion?

• A) A mutation where a chromosome duplicates itself.

• B) A mutation where two segments of the same chromosome swap places.

• C) A mutation where a chromosome loses a segment.

• D) A mutation where a chromosome attaches to another chromosome.

During a chromosomal inversion, the segments that swap places are from:

• A) Different chromosomes.

• B) The same chromosome.

• C) Non-homologous chromosomes.

• D) All chromosomes in the cell.

What occurs during a chromosomal translocation?

• A) A chromosome duplicates itself.

• B) A part of one chromosome breaks off and attaches to another nonhomologous chromosome.

• C) Two chromosomes exchange entire segments.

• D) A chromosome loses a part of its DNA.

Can translocations involve the exchange of segments between chromosomes?

• A) Yes, but only within homologous chromosomes.

• B) No, translocations do not involve the exchange of segments.

• C) Yes, sometimes segments are swapped so that two translocations occur at the same time.

• D) Yes, but it results in the deletion of genes.

What is translocation in the context of chromosomal mutation?

• The process by which a chromosome is duplicated.

• The process by which random parts of chromosomes break off and attach to other chromosomes.

• The removal of certain parts of a chromosome.

• The process by which chromosomes are exchanged between non-homologous pairs.
