B)Gene chip
C)Genome sequencing
D)White blood cell count

Question

Quizplus · Accepted Answer

Fluorescence in situ hybridization (FISH) is a technique that allows for the detection of specific DNA sequences in chromosomes. It is a useful tool in detecting chromosomal abnormalities, as well as identifying the presence of specific genes or regions of DNA. In this case, the replication of a particular chromosomal region could be detected using FISH, making it the most appropriate technique for this purpose. Gene chip and genome sequencing are useful in detecting mutations or variations in DNA sequences but may not specifically detect replication of a particular chromosomal region. White blood cell count is not related to identifying chromosomal abnormalities or replication.
