The storage temperature depends on how long the seeds are to be kept. Durations of 3–5 years (short term storage), 10-15 years (medium term storage) and 50+ years (long term storage) will typically have storage temperatures of 5 to 10 °C (41 to 50 °F), 0 °C (32 °F) and −18 to −20 °C (0 to −4 °F) respectively.
Current Protocols is a series of laboratory manuals for life scientists. The first title, Current Protocols in Molecular Biology, was established in 1987 by the founding editors Frederick M. Ausubel, Roger Brent, Robert Kingston, David Moore, Jon Seidman, Kevin Struhl, and John A. Smith of the Massachusetts General Hospital Department of Molecular Biology and the Harvard Medical School ...
[4] Multiplex-PCR consists of multiple primer sets within a single PCR mixture to produce amplicons of varying sizes that are specific to different DNA sequences. By targeting multiple sequences at once, additional information may be gained from a single test run that otherwise would require several times the reagents and more time to perform.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.
In biology, explant culture is a technique to organotypically culture cells from a piece or pieces of tissue or organ removed from a plant or animal. The term explant can be applied to samples obtained from any part of the organism.
During meiosis, 5 of X form one chain, and 5 of Y form another chain. Thus, they behave effectively as a typical XY chromosomal system, except each of X and Y is broken into 5 parts, with the effect that recombinations occur very frequently at 4 particular points. [17]
The terms animal testing, animal experimentation, animal research, in vivo testing, and vivisection have similar denotations but different connotations.Literally, "vivisection" means "live sectioning" of an animal, and historically referred only to experiments that involved the dissection of live animals.
