A term commonly used to describe a crumbling or fragmenting callus. A friable callus is easily dissected and readily dispersed into single cells or clumps of cells in solution.
Industry:Biotechnology
A term describing a micro-organism that is capable of assimilating (or taking up) hydrogen gas.
Industry:Biotechnology
A term describing substances that are diffusable and that can affect spatially separated entities within cells.
Industry:Biotechnology
A term referring to biological units that cannot function by themselves; such units require the assistance of another unit, or "helper".
Industry:Biotechnology
A term used in both classical and molecular genetics.
1. In classical genetics: An organism or cell that is the result of recombination (crossing-over), e.g., Parents: <i>AB</i>/<i>ab</i> and <i>ab</i>/<i>ab</i>; recombinant offspring: <i>Ab</i>/<i>ab</i>.
2. In molecular genetics: A molecule containing DNA from different sources. The word is typically used as an adjective, e.g., recombinant DNA.
Industry:Biotechnology
A term used to describe any process or enzyme which acts at a defined sequence within a DNA or RNA molecule. Type II restriction enzymes are site-specific endonucleases and the recombination systems encoded by some transposons are site-specific, such as is the integration of phage into the <i>E. coli</i> chromosome.
Industry:Biotechnology
A term used to describe nucleic acid molecules consisting of only one polynucleotide chain. The genomes of certain phages, e.g., MI3, are single-stranded DNA molecules; rRNA, mRNA and tRNA are all single-stranded nucleic acids, but they all contain double-stranded regions formed by the intra-strand base-pairing of self-complementary sequences.
Industry:Biotechnology
A term used to describe RNA molecules joined <i>in vitro</i> by T4 RNA ligase.
