|
chloroplast DNA (cpDNA)
|
DNA in chloroplasts; has many characteristics in common with eubacterial DNA and typically consists of a circular molecule that lacks histone proteins and encodes some of the rRNAs, tRNAs, and proteins found in chloroplasts
|
580
|
|
|
D loop
|
region of mitochondrial DNA that contains an origin of replication and promoters; it is displaced during the initiation of replication, leading to the name displacement, or D, loop
|
586
|
|
|
endosymbiotic theory
|
states that some membrane-bounded organelles, such as mitochondria and chloroplasts, in eukaryotic cells originated as free-living eubacterial cells that entered into an endosymbiotic relation with a eukaryotic host cell and evolved into the present day organelles; supported by a number of similarities in structure and sequence between organelle and eubcteral DNAs
|
584
|
|
|
heteroplasmy
|
presence of two or more distinct variants of DNA within the cytoplasm of a single cell
|
581
|
|
|
homoplasmy
|
presence of only one version of DNA within the cytoplams of a single cell
|
581
|
|
|
mitochondrial DNA (mtDNA)
|
DNA in mitochondria; has some characteristics in common with eubacterial DNA and typically consists of a circular molecule that lacks histone proteins and encodes some of the rRNAs, tRNAs, and proteins found in mitochondria
|
579
|
|
|
replicative segregation
|
random segregation of organelles into progeny cells in cell division. If two or more versions of an organelle are present in the original cell, chance determines the proportion of each type that will segregate into each progeny cell
|
581
|
|
|
tetrad
|
the four products of meiosis; all four chromatids of a homologous pair of chromosomes
|
589
|
|
|
tetrad analysis
|
genetic analysis of a tetrad, the products of a single meiosis
|
