Question 14

Using fluorescent probes, the method known as ? That targets certain DNA sequences and makes them visible on the chromosomes. It has a better sensitivity for abnormalities than traditional karyotyping, and it can pick up on minor deletions or duplications that bands would miss.

Answer 14

fluorescence in situ hybridization (FISH)

Question 15

Another method that employs microarrays to compare the
DNA content of two samples, such as healthy and cancerous cells, is called ? By detecting copy number variations (CNVs) that karyotyping could miss, it can offer a genome-wide perspective of genetic alterations

Answer 15

comparative genomic hybridization (CGH)
