Protein Synthesis Race. DNA Interactives. HMMI BioInteractive DNA. Animation Adenine (A), cytosine (C), guanine (G), and thymine (T) are the components of nucleic acid that make up DNA. In 1950, Erwin Chargaff published a paper stating that in the DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This became known as Chargaff's ratio, and it was an important clue for solving the structure of DNA. Chronic myeloid leukemia (CML) is caused by a mutation that leads to an abnormal protein that is always active. The drug Gleevec has a shape that fits into the active site of the abnormal protein and stops its harmful effects.
Of the 3 billion letters in the human genome, only 1% directly code for proteins. Reactive molecules, such as free radicals, and solar ultraviolet radiation can lead to mutations in DNA. A new gene can be inserted into a loop of bacterial DNA called a plasmid. The public Human Genome Project started by identifying unique marker sequences distributed throughout the genome. Video Clips. Protein Synthesis - long. DNA from the Beginning - animated experiments. DNA from the Beginning is organized around key concepts. The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links.
DNAftb blog: It's the season of hibernation, something I've always wished I could do. Oh, to wrap up in a ball, sleep away the winter, and wake to a beautiful spring day – like Bambi! Feature: We have relaunched the Weed to Wonder site as a flexible "e-book" that can be viewed as a website, an app, or a printable PDF.
