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 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 .

Genetic inheritance was first discovered by Gregor Mendel in 1865, following experiments crossing peas. [3] In 1928 Frederick Griffith proved the existence of a "transforming principle" involved in inheritance, which was identified as DNA in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty .
VHS-C is a downsized version of VHS, using the same recording method and the same tape, but in a smaller cassette. It is possible to play VHS-C tapes in a regular VHS tape recorder by using an adapter. After the introduction of S-VHS, a corresponding compact version, S-VHS-C, was released as well. Video8 is an indirect descendant of Betamax ...

Films about genetic engineering, the direct manipulation of an organism's genes using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms .
The classic example of genetic assimilation was a pair of experiments in 1942 and 1953 by Waddington. He exposed Drosophila fruit fly embryos to ether, producing an extreme change in their phenotype: they developed a double thorax, resembling the effect of the bithorax gene. This is called a homeotic change.
