Codis

System used by FBI to compare dna profiles, 12 codis sited per person each codis site has 1/10 chance of matching someone else

PCR

polymerase chain reactions (create more dna copies to study)

STR

Short tandem repeats, measure repeating of 4 nucleotide dna repeat

Gel electrophoresis

Used to identify dna

1. Dna is cut by restriction enzymes

2. DNA is put in wells across from positive charge

3. Energy is added and dna is negatively charge so It moves

4. Long pieces sink and go less far short pieces go farther

Restriction enzymes

Cut dna at known location

Snp

Single nucleotide variation

Flanking Region

Non coding dna before and after genes

Gêne therapy vs gene engineering

Gêne therapy correcte genetic defects to prevent genetic disease. Gene editing modify genes to enhance beyond what’s normal

CRISPR

Highly precise gene editing tool that targets a 20 ish nucleotide sequence to cut and replace
