| Question | Answer |
|---|---|
| The Human Genome Project | Genetic and physical mapping of chromosomes and DNA sequencing |
| Noncoding DNA | Repetitive nucleotide sequences "junk DNA" |
| How many genes do humans have compared to other organisms? | Humans have about the same amount, some plants and animals have more genes than humans |
| Restriction Enzymes | -Endonucleases -Made by bacteria to cut out foreign DNA -Cuts DNA at specific sequences |
| What happens at the end of DNA Fingerprinting? | A DNA fingerprint is made |
| What are the steps of DNA Fingerprinting? | -DNA is isolated -Restriction enzymes are added -DNA becomes negatively charged -Positive electrode attracts the DNA -Fragments move to create a unique pattern |
