Question

The chromosome undergoes a translocation mutation during its replication. Which image best represents the translocation?

Answer 1

The best representation of a translocation mutation is an image illustrating nonhomologous chromosomes with a segment of DNA transferred from one to the other, indicative of a reciprocal translocation as in Figure 15.17.

Step-by-step explanation:

The student's question revolves around translocation mutations in chromosomes, specifically during the replication process. A translocation is a type of chromosomal mutation that involves a segment of DNA being transferred from one chromosome to another nonhomologous (not with the same gene sequence) chromosome. This type of mutation can be implicating in the development of certain cancers, such as chronic myelogenous leukemia, where chromosomal regions become abnormally fused at a characteristic location, resulting in the production of oncogenic proteins.

Based on the information given, the best representation of a translocation mutation would be an image showing two nonhomologous chromosomes with a DNA segment transferred from one to the other, resembling Figure 15.17 as described. This figure illustrates a reciprocal translocation where a segment of DNA is transferred between nonhomologous chromosomes, which is a specific example of translocation mutation.

Answer 2

It is possible to represent this process graphically by changing the color of the genomic fragment that has been translocated into a new genomic location. Thus, it is simple to observe that a translocation produces a deletion of the genomic fragment and its new localization in the chromosome
