Genetic engineering

variable domains

Biotechnology; Genetic engineering

Regions of antibody chains that have different amino acid sequences in different antibody molecules. These regions are responsible for the antigen-binding specificity of the antibody molecule.

constant domains

Biotechnology; Genetic engineering

Regions of antibody chains that have the same amino acid sequence in different members of a particular class of antibody molecules.

heterochromatin

Biotechnology; Genetic engineering

Regions of chromosomes that stain darkly even during interphase; thought to be for the most part genetically inactive. cf euchromatin.

consanguinity

Biotechnology; Genetic engineering

Related by descent from a common ancestor.

weed

Biotechnology; Genetic engineering

Simply any plant growing where it is not wanted. In agriculture, used for a plant which has good colonizing capability in a disturbed environment, and can usually compete with a cultivated species ...

Okazaki fragment

Biotechnology; Genetic engineering

Since DNA can be replicated in only one direction, i.e., nucleotides can be added only at the 3´ end, only one of the two strands of a double helix can be replicated continuously. The other strand is ...

algal biomass

Biotechnology; Genetic engineering

Single-celled plants, such as Chlorella spp. and Spirulina spp., are grown commercially in ponds to make feed materials. Chlorella is grown commercially to make into fish food: it is fed to ...
