Non-Mendelian Inheritance Mitochondrial DNA (mtDNA) : DNA in mitochndria; has ome 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 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 afound in chloroplasts Heteroplasmy :the occurrence of two distinct varieties of DNA within the cytoplasm of a single cell Replicative Segregation : random segregation of organelles in to progeny cells in cell division. If two or more versions of an organelle are present in the original cell, chance

Unformatted text preview: determines the proportion of each type that will segregate into progeny cell Homoplasmy : presence of only one version of DNA within the cytoplasm of a single cell Endosymbiotic Theory : proposes that mitochondria and chloroplasts were once free-living bacteria that became internal inhabitants (endosymbionts) of early eukaryotic cells D loop : the region of mitochondrial DNA where the origin of replication for the H strand is located and also contains promoters for both the H and the L strands. Is displaced during the initiation of replication , leading to the name diplacement, or D loop Tetrad : the four cells produced by a single meiotic division; all four chromatids of a homologous pair of chromosomes Tetrad Analysis : the genetic analysis of a tetrad...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
