    Study Notes

    1. DNA is found in both plants and animals, with two types being nuclear and mitochondrial.
    2. Mitochondrial DNA is more prevalent and stable, and can only link individuals by maternal lineage.
    3. The human genome project mapped out the human genome over 13 years.
    4. Cells contain 23 pairs of chromosomes located in the nucleus, with XX chromosomes in females and XY in males.
    5. Genes are composed of DNA and create thousands of different proteins.
    6. DNA strands can have millions of bases, with 30% being tandem repeats.
    7. Polymerase chain reaction (PCR) is a technique for replicating or copying DNA strands.
    8. Hair characteristics vary by body part and race, and can be compared through morphological or DNA analysis.
    9. Morphological analysis is presumptive in nature, and DNA analysis is the best method to test hair.
    10. Hair growth occurs in three phases: anagen, catagen, and telogen.
