DNA sample collection

DNA sample collection involves obtaining a small amount of biological material, such as blood, saliva, or cheek cells, which contain DNA. The process is typically quick and minimally invasive. For example, a cheek swab gently brushes the inside of the mouth to gather cells, while blood samples are drawn with a needle. The collected sample is then preserved and sent to a lab, where it’s processed to extract and analyze the DNA. This procedure helps in identifying individuals for forensic, medical, or investigative purposes with accuracy and efficiency.
