PCR-polymerase Chain reaction DNA
 * technique used to make copies of DNA-Amplification
 * Advantage-the amplification process be limited to specific areas of the sequence
 * means deoxyribonucleic acid
 * inherit from mom and dad
 * the genetic instructions
 * tells who the person is and about the person
 * where is DNA found
 * in the cell
 * cell types (carry same DNA)
 * blood
 * hair roots
 * sweat
 * semen
 * various tissues

Source of biology evidence
 * nuclear DNA
 * comes from both parents
 * makes who we are as a person
 * Mitochondrial DNA
 * Only comes from the mother
 * Where is DNA in body
 * in the nucleus
 * What does it look like
 * double helix
 * what makes it up
 * a-adenine
 * T-Thymine
 * G-Guanine
 * C-Cytosine
 * blood,semen,saliva,urine,hair, teeth,bone,and tissue
 * amplification-making copies
 * /PCR cycle
 * step 1. denature through heat breaks DNA apart
 * step 2. anneal-actually making the copy
 * get a primer focus on common part and add enzyme and add DNA single pairs


 * step 3. extend-adding on to what is already there
 * step 4. amplificationbreak apart each time 28 times 1 copy goes to 4 copes 4 copies go to 8 copies etc etc.
 * step 5. analyze and DNA profile is given
