that encodes for a taste receptor that allows for PTC to be tasted - ✔✔Hae III
If both copies are different - ✔✔Heterozygous

Electrophoresis is? - ✔✔the movement of a charged molecule in an electrical field
, Dna is _____charged? - ✔✔negatively
The agarose gel does what to the movement of the DNA ? - ✔✔slows the movement of the
negatively-charged DNA molecule; the larger the molecule, the harder time it has getting
through the gel. Therefore small molecules migrate relatively quickly to the positive pole and
larger molecules move more slowly
How does bacteria replicate? - ✔✔Asexually by binary fission: ability to incorporate new
genetic material from surroundings
What is transformation? - ✔✔ability to bind naked DNA in the environment and absorb it ?

Bacteria are grown in? - ✔✔Media
Where are bacteria easily grown? - ✔✔In LB broth and or agar
What is competent? - ✔✔ability to take up the plasmid
What is chemical competancy - ✔✔induced in E.Coli by testing with chloride salts of metal
cation calcium,magnesium and rubidium. Assistance of sudden cycles of heat and cold
