Molecular biology

A stack of flattened vesicles that functions in the post-translational processing and sorting of proteins. The Golgi receives proteins from the rough endoplasmic reticulum (RER) and directs them to ...

equilibrium model

Biology; Biochemistry

In evolution theory, phyletic gradualism, the proposition that evolution occurs at a slow and generally constant rate involving a large fraction of an entire species that gradually separates from the ...

aggregation

Biology; Biochemistry

The formation of higher-molecular-mass species due to non-covalent adherence of smaller species. Especially for proteins, aggregation is a form of denaturation in which non-polar surfaces of ...

altered-self hypothesis

Biology; Biochemistry

The proposal that helper T-cells recognize a foreign material, e.g. a viral antigen, when it is presented on the surface of an antigen-presenting cell as a complex with the major histocompatibility ...

loss of heterozygosity (LOH)

Biology; Biochemistry

A test for chromosomal changes in tumor DNA and the theory that some tumors arise from inactivation of both alleles for an anti-oncogene. Heterozygotes, who already have one mutation, are most ...

phage-display

Biology; Biochemistry

A method for incorporation, into the DNA that encodes a phage coat protein, of a polypeptide, where it is available for a selection procedure; especially for production and selection of antibody ...

molecular resonance force microscopy (MRFM)

Biology; Biochemistry

A technique similar to atomic force microscopy, which, in theory, can detect and map magnetic resonance in paramagnetic nuclei of macromolecules. The MRFM resonator probe, mounted on a flexible ...
