Chromosome Conformation

Capture Chromosome Conformation Capture (3C) is a powerful tool used to detect physical interactions between different sites within a chromosome. The technique relies on crosslinking DNA molecules that are brought into close proximity through physical contact, followed by digestion using restriction enzymes and ligation. The ligation products are then amplified using PCR, and the amount of ligation product measured by quantitative PCR. 3C provides valuable information about the three-dimensional structure and organization of chromosomes, which is necessary to better understand how the genome is regulated. The technique has wide applications in genome-wide studies, such as mapping regulatory elements and non-coding RNAs, understanding epigenetic modifications, and examining the role of chromosomal rearrangements in disease. 3C is an integral part of modern genomics and provides a powerful tool for exploring the structure-function relationships of chromosomes.
