Question

a medical researcher is trying to develop a diagnostic technique for a disease which is characterized by replication of a particular chromosomal region. what would be the most appropriate technique? multiple choice genome sequencing white blood cell count gene chip fish

Explanation:

Fluorescence in - situ hybridization (FISH) is a powerful technique for detecting and mapping specific DNA sequences on chromosomes. It can identify chromosomal abnormalities such as duplications (replications) of particular regions. Genome sequencing is more for determining the entire DNA sequence. White - blood cell count is related to immune - system status and not for detecting chromosomal region replication. Gene chips are mainly used for gene expression analysis rather than directly detecting chromosomal region replication.

Answer:

D. FISH
