Final answer:
The correct answer is C) Gene locus, which refers to the specific location on a chromosome where a particular gene is found and can be subjected to genomic amplification.
Step-by-step explanation:
The question is asking which part of chromosome 1 might be amplified, and the correct answer is C) Gene locus.
Large scale mutations in chromosomes can include the gain of portions of a chromosome, known as genomic amplification, typically involving a chromosomal locus and potentially leading to the development of conditions like cancer if oncogenes are involved. We focus on gene locus as the region of DNA within a chromosome where a particular gene is found. While the centromere is the central part important for chromosome separation during cell division, and the telomere is the protective end part of a chromosome that does not typically code for genes, microsatellites are repeated sequences of DNA. Therefore, when referring to amplification of regions of DNA, the gene locus is the most appropriate term as it specifies the location on a chromosome where a particular gene is situated.
