Human evolution

Metaphase II

Archaeology; Human evolution

The second stage of meiosis during which the centromeres line up on the equator of the second-division spindles (in each of two daughter cells formed from meiosis I).

Prophase II

Archaeology; Human evolution

The second stage of meiosis during which there is chromosome contraction.

The single (double stranded) DNA molecule that controls the development and functioning of the mitochondrion containing it. Because reproduction is by cloning, mtDNA is usually passed along female ...

RDNA repeat units

Archaeology; Human evolution

The tandem arrays of rRNA genes, 18S-5.8S-28S, repeated many times along the chromosome.

Non-Mendelian inheritance (cytoplasmic inheritance)

Archaeology; Human evolution

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 ...

Precursor mRNA (primary transcripts; pre-mRNA)

Archaeology; Human evolution

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' ...

Precursor RNA molecule (primary transcripts; pre-RNA)

Archaeology; Human evolution

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.
