In many eukaryotic organisms such as humans the genome is tightly packed and organized with the help of nucleosomes chromatin. Baquerizo birth marisol 2016 exploring teachers perspectives on the impact of out of school science based programs for secondary level physics classrooms in nebraska. Mtdna is generally passed un mixed from mothers to children of both sexes along the maternal line or matrilineally.
Mitochondrial dna mtdna and y chromosome dna are commonly used to trace ancestry in this manner.

Genomic dna mitchondrial dna. Most of the dna can be found in the cell nucleus and in plants and algae also in plastids such as. A nucleosome is a complex formed by eight histone proteins that is wrapped with 147bp of dna when the dna is being actively transcribed into rna the dna will be opened and loosened from the nucleosome complex. Mitochondrial dna is only a small portion of the dna in a eukaryotic cell.
