Question

Quizplus · Accepted Answer

Fragile sites are specific areas on chromosomes that have a higher tendency to form gaps or breaks when cells are cultured under certain conditions. These sites are not due to proteins bound to the chromosome but are related to specific nucleotide sequences that make the chromosome structure more susceptible to breakage.
