A point mutation in which one base pair in the DNA sequence is replaced by another.
Industry:Biotechnology
A polymer having the general formula: HOCH<sub>2</sub>(CH<sub>2</sub>OCH<sub>2</sub>)XCH<sub>2</sub>OH and available in a range of molecular weights from <i>ca</i> 1000 to <i>ca</i> 6000. PEG 4000 and PEG 6000 are commonly used to promote cell or protoplast fusion, and to facilitate DNA uptake in the transformation of organisms such as yeast. PEG is also used to concentrate solutions by withdrawing water from them.

Industry:Biotechnology
A polypeptide made from a recombinant gene that contains portions of two or more different genes. The different genes are joined so that their coding sequences are in the same reading frame: the genetic apparatus reads the gene fusion as a single gene, and so produces a fusion protein. Also known as hybrid protein or chimeric protein. These proteins are used:
- to add an affinity tag to a protein;
- to produce a peptide as part of a larger protein, which is then cut up after it has been made by cloning;
- to produce a protein with the combined characteristics of two natural proteins; or
- to produce a protein where two different activities are physically linked.
Industry:Biotechnology
A polyploid that has multiple and identical or nearly identical sets of chromosomes (genomes) all derived from the same species. A polyploid species with genomes derived from the same original species.
Industry:Biotechnology
A polysaccharide comprising highly branched chains of glucose molecules. The water-insoluble portion of starch.
Industry:Biotechnology
A polysaccharide consisting of linear chains of 100 to 1000 glucose molecules. The water-soluble portion of starch.
Industry:Biotechnology
A population of different DNA molecules encoding peptides, that has been cloned into one kind of expression vector.
Industry:Biotechnology
A population of plant or animal cells or micro-organisms that is grown under controlled conditions.
