Applications of DNA technologies (video) | Khan Academy
DNA technology revolutionizes medicine, forensics, and agriculture. Recombinant DNA creates insulin and growth hormones, improves vaccine safety, and helps solve crimes through genome analysis.
Bacterial transformation & selection (article) | Khan Academy
Transfer of plasmid DNA into bacteria. How bacteria are selected. Protein production and purification.
DNA cloning and recombinant DNA (video) | Khan Academy
DNA cloning involves creating identical copies of a specific gene using restriction enzymes to cut the desired gene, pasting it into a plasmid, and inserting it into bacteria like E. coli. The bacteria replicate …
Gel electrophoresis (video) | Biotechnology | Khan Academy
Gel electrophoresis is a technique used to separate DNA, RNA, or protein fragments by size. It involves a gel, electric charge, and migration of molecules. DNA samples are placed in wells within an …
Displacement (article) | Kinematics | Khan Academy
An object's position is its location relative to a chosen reference frame. Position is a vector with both magnitude and direction. The variable x → is often used to represent horizontal position. The …
Restriction enzymes & DNA ligase (article) | Khan Academy
How can pieces of DNA from different sources (such as a human gene and a bacterial plasmid) be joined together to make a single DNA molecule? One common method is based on restriction …
Transcription: an overview of DNA transcription (article) | Khan Academy
The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein …
