Gel electrophoresis - a technique used to separate DNA fragments according to their size; DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel; DNA fragments are negatively charged, so they move towards the positive electrode; ex: paternity testing or forensics, Polymerase chain reaction (PCR) - a technique to make many copies of a specific DNA region in a test tube; the reaction is repeatedly cycled through a series of temperature changes, which allow many copies of the target region to be produced; ex: COVID testing, DNA cloning - a molecular biology technique that makes many identical copies of a piece of DNA, such as a gene; ex: Dolly the sheep, DNA sequencing - the process of determining the sequence of nucleotides (As, Ts, Cs, and Gs) in a piece of DNA; ex: Human Genome Project,
