Molecular biology

A hypothetical explanation of evolution, that successful organisms, over time, will crowd out and displace less successful ones, or will be better adapted to different niches and, over time and by ...

ascus

Biology; Biochemistry

A spore-like form through which yeast cells pass during their life cycle; an outer wall surrounds a diploid cell that undergoes meiosis to form four haploid cells (ascospores) which eventually ...

anaplerotic pathway

Biology; Biochemistry

Metabolic reactions that replenish the pools of intermediates of the tricarboxylic acid cycle. These pools may become depleted, as they also serve as precursors for amino acid synthesis, ...

antigen presentation

Biology; Biochemistry

The appearance on the surface of a cell of a foreign protein, e.g. one that arises from viral infection, in a complex with a class I major histocompatibility complex protein. It is this complex that ...

chloride shift

Biology; Biochemistry

The movement of chloride ions into erythrocytes as bicarbonate exits, due to the generation by carbonic anhydrase of bicarbonate from carbonic acid inside the cells as they pass through peripheral ...

wobble

Biology; Biochemistry

The presumed slackness of structural requirements for complementarily in fitting codon to anticodon that permits several bases in the third position of the codon to pair with a particular base in the ...

nitrogen fixation

Biology; Biochemistry

The reduction of molecular nitrogen to ammonia and nitrogen-containing metabolites that is carried out synthetically, or naturally by blue-green algae or bacteria, e.g. Rhizobium species that inhabit ...
