Manipulating and Cloning DNA
Being Healthy Type 1 diabetes Type 2 diabetes How can you help these individuals?
Insulin Banting and Best – Pigs and cows Helen Free Allergic reaction to insulin from pigs and cows Genetic engineering – Inserted into bacteria – Produced insulin from humans
Why Bacteria? Reproduce quickly Plasmids Form recombinant DNA – Restriction enzymes – Sticky ends vs. blunt ends – Restriction fragments Sticky or Blunt ends?
How Do You Know Where to Cut? Restriction enzymes recognize recognition sites – Sticky ends & blunt ends Restriction map
We Are Family Vector + foreign material = recombinant DNA – Plasmids Competent/host cell takes up recombinant DNA – Bacteria Restriction enzymes cut DNA ligase reforms backbone
