D) Chromosome painting
E) Classical karyotyping

Question

Quizplus · Accepted Answer

Chromosome painting is a technique in which fluorescently labeled DNA fragments that have been isolated and characterized in the laboratory are used to create colorful chromosome images. This technique is commonly used in research to identify chromosomal abnormalities and to study chromosome evolution. Giemsa staining, Quinacrine staining, and Gram staining are all traditional staining methods used in microscopy, but they do not involve the use of fluorescent DNA probes. Classical karyotyping is a technique for analyzing the number and structure of chromosomes in a cell, but it does not involve the use of fluorescent DNA probes.
