However, for research and diagnostic purposes, here are some common cell types used for DNA extraction:
* Blood: White blood cells in blood are a readily accessible source of DNA.
* Saliva: Saliva contains epithelial cells that can be used to extract DNA. This method is often used for at-home DNA testing kits.
* Buccal swab: A swab taken from the inside of the cheek collects epithelial cells for DNA extraction.
* Hair follicles: Hair follicles contain DNA, but the extraction process is more complex than other methods.
* Skin cells: Cells from the skin can be used for DNA extraction, though this is less common than other methods.
Important Note: Ethical considerations and legal regulations strictly govern the collection and use of human DNA. DNA extraction should only be performed by qualified professionals in a controlled setting.
