Human evolution

cell-free, protein-synthesizing system

A system, isolated from cells, that contains ribosomes, mRNA, tRNAs with amino acids attached, and all the necessary protein factors for the in vitro synthesis of polypeptides.

patrilineal descent

Archaeology; Human evolution

Descent traced through a line of ancestors in the male line (see agnatic descent).

point mutants

Archaeology; Human evolution

Organisms whose phenotypes result from an alteration of a single nucleotide pair.

homeodomain

Archaeology; Human evolution

The 60-amino-acid part of proteins that corresponds to the homeobox sequence of genes. All homeodomain-containing proteins appear to be located in the nucleus.

environmental sex determination

Archaeology; Human evolution

The process by which the environment plays a major role in determining the sex of an organism.

cloning vector (cloning vehicle)

Archaeology; Human evolution

A double-stranded DNA molecule that is able to replicate autonomously in a host cell and with which a DNA fragment (or fragments) can be bonded to form a recombinant DNA molecule for cloning.

crest

Archaeology; Human evolution

A ridge with a sharp edge caused by muscle pull. A simple crest is created by the unidirectional pull of a single muscle, a compound crest by the opposing pulls of two muscles.
