A mutation accumulation (MA) experiment is a genetic experiment in which isolated and inbred lines of organisms (so-called MA lines) are maintained such that the effect of natural selection is minimized, with the aim of quantitatively estimating the rates at which spontaneous mutations (mutations not caused by exogenous mutagens) occur in the studied organism.
The BBC solved the problem by using 52-centimetre (20 in) reels of magnetic tape that passed static heads at a speed of 5.08 metres per second (16.7 ft/s). VERA was capable of recording about 15 minutes (e.g. 4,572 meters) of 405-line black-and-white video per reel, and the picture tended to wobble because of some jitter (uneven speed) of the ...
The experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymers to translate specific amino acids. In the experiment, an extract was prepared from bacterial cells that could make protein without the presence of intact living cells .
In the 1940s and early 1950s, experiments pointed to DNA as the portion of chromosomes (and perhaps other nucleoproteins) that held genes. A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics .

It required the use of a home video tape recorder for storage. [17] November 4–7, 1977: 3M demonstrates a prototype 2-channel 50.4 kHz 16-bit digital recorder running on 1-inch tape at 45 ips at the New York AES Convention. [3] As no true 16-bit converters were available, it combined separate 12-bit and 8-bit converters to create 16-bit ...
