INTERNUCLEOSOMAL DNA FRAGMENTATION Meaning and
Definition
-
Internucleosomal DNA fragmentation refers to a specific type of DNA breakdown that occurs within the nucleus of cells. It is characterized by the cleavage of DNA into distinct fragments approximately 200 base pairs in length, which are separated by nucleosomes. This process is a fundamental feature of programmed cell death, also known as apoptosis.
During apoptosis, cells undergo a highly regulated and controlled process of self-destruction. Internucleosomal DNA fragmentation is one of the hallmark features of this process and plays a crucial role in the removal of damaged or unwanted cells. The DNA fragmentation occurs due to the activation of specific enzymes called endonucleases, which cleave the DNA at specific nucleotide sequences.
The resulting DNA fragments are approximately 200 base pairs long and are bounded by nucleosomes, which are protein complexes involved in DNA packaging. The internucleosomal DNA fragmentation can be visually detected using techniques such as gel electrophoresis, where the distinct DNA fragments appear as a characteristic ladder-like pattern.
This type of DNA fragmentation is commonly used as a biochemical marker to confirm the occurrence of apoptosis and distinguish it from other forms of cell death. It is frequently employed in both research and clinical settings to study the mechanisms underlying apoptosis and to assess its role in various physiological and pathological processes, including tissue development, immune response, and cancer.
