- Company Profile:
A cusp pattern found in lower molars in which there are five main cusps separated by grooves, and the mesiolingual and distobuccal cusps touch.
Industry:Archaeology
A DNA replication involving the synthesis of short DNA segments, which are subsequently linked to form a long polynucleotide chain.
Industry:Archaeology
A extension of Mendel's laws of inheritance that describes the expected relationship between gene frequencies in natural populations and the frequencies of individuals of various genotypes in the same populations.
Industry:Archaeology
The first stage of meiosis. There are several stages of phophase I, including leptonema, zygonema, pachynema, diplonema, and diakinesis.
Industry:Archaeology
The generalization that new adaptations are often allowed by evolutionary changes that initially better adapt a species to its old way of life.
Industry:Archaeology
The generalization that there is a steady increase in size in phyletic series.
Industry:Archaeology
The inheritance of characters determined by genes not located on the nuclear chromosomes but on mitochondrial or chloroplast chromosomes. Such genes show inheritance patterns distinctively different from those of nuclear genes.
Industry:Archaeology
The initial transcript of a gene that is modified and/or processed to produce the mature, functional mRNA molecule. In eukaryotes, for example, the transcript is modified at both the 5' and the 3' ends, and in a number of cases RNA sequences that do not code for amino acids are present and must be excised.
Industry:Archaeology
The initial transcript whose processing may involve the addition and/or removal of bases, the chemical modification of some bases, or the cleavage of sequences from the precursor.
