Document Summary

Segments of dna that code for proteins: proteins: functional building blocks of cells. Most of cell"s dna is located w/in nucleus, but mitochondrial dna (mtdna) is found in mitochondrion: mitochondrion: cell structure responsible for converting energy into usable forms for the body, each cell may contain hundreds of mitochondria. There are many more copies of mtdna per cell than nuclear dna b/c there"s only one nucleus per cell. Mtdna is also unique from nuclear dna b/c it"s only passed down through maternal line of inheritance. This is helpful to forensic scientists b/c they can refer to mtdna of female relatives for genetic info: short tandem repeats (strs): Portions of dna estimated to comprise approximately 30% of the human genome. Don"t code for any translated genetic material. Don"t affect human phenotype (physical appearance): they"re one of the most effective ways to analyze genetic content b/c it"s.
