Mo5-L2c: Why are Disease Inherited?
Bacteria have been genetically engineered to
produce human insulin.
DNA
Chromosome DNA loop
A portion of the
DNA loops is cut
and removed
Insulin gene from
Remaining DNA human chromosome
from original DNA is inserted into the
original DNA
Recombinant
DNA formed.
Another bacterial cell Insulin
takes up recombinant Produced
DNA
SUMMARY
Why are Diseases Inherited?
Scientists use genetic engineering to help
treat diseases and learn more about how
organisms develop.
Scientists use models like Punnett squares
and pedigrees to predict and show patterns in
inheritance that can be used to figure out why
these diseases are passed on.
