Which of the following can cause reciprocal translocations to occur?
A
Vitamin deficiency
B
High protein diet
C
Ionizing radiation
D
Excessive exercise
Verified step by step guidance1
Understand the concept of reciprocal translocations: Reciprocal translocations occur when segments from two different chromosomes are exchanged. This can lead to genetic abnormalities if the exchange disrupts important genes.
Identify the causes of reciprocal translocations: These can be caused by factors that induce breaks in the DNA strands, allowing for the exchange of chromosome segments.
Consider the role of ionizing radiation: Ionizing radiation is known to cause DNA damage by breaking the DNA strands, which can lead to chromosomal rearrangements such as reciprocal translocations.
Evaluate the other options: Vitamin deficiency, a high protein diet, and excessive exercise are not typically associated with causing DNA strand breaks or chromosomal rearrangements.
Conclude that ionizing radiation is the most likely cause of reciprocal translocations among the given options, due to its ability to induce DNA strand breaks.
