Cards

Term
Why are restriction enzymes used?
Definition
Used to cut and degrade viruses that enter their cells.
Term
Why is bacteria a good choice for transformation?
Definition
Single celled, use plasmid DNA, and reproduce quickly
Term
Roles for each step
Definition
1.)CaCl₂treatment (TS)-positive charge of CA₂+ neutralizes negative charge of DNA and cell membrane
2.)Incubation on ice-slows cell membranes
3.)Heat-shock-increases permeability of cell membrane
(2 and 3 allow plasmid to be taken in by bacteria cells)
4.)Nutrient broth incubation-allows beta lactamase gene to be expressed (for antibiotic resistance)
Term
What genes are contained in the pGLO plasmid?
Definition
Beta lactamase, green fluorescent protein, and araC regulator protein
Term
Alcoholic Fementation
Definition
Produces carbon dioxide and alcohol; causes bread dough to rise
Term
Lactic Acid Fermentation
Definition
Produces lactic acid; produced in muscles when body can't supply enough oxygen to the tissues
Term
Photosynthesis Equation
Definition
6CO₂+ 6H₂0 ----> C₆H₁₂ O₆ + 6O₂
(Carbon dioxide + water --light--> sugars + oxygen)
Term
Cell Respiration Equation
Definition
60₂+ C₆H₁₂O₆---> 6CO₂+6H₂O + Energy
(Oxygen + glucose---> carbon dioxide + water + energy)
Term
What is alternation of generations?
Definition
Process in which many algae switch back and forth between haploid and diploid stages of their life cycles.
Term
What to plants need to survive on land?
Definition
Sunlight, water, minerals, gas exchange, and the transport of water and nutrients throughout the plant body.
Term
What does phloem carry?
Definition
Solutions of nutrients and carbohydrates produced by photosynthesis
Term
What does xylem carry?
Definition
Water upward from the roots to every part of a plant.
Term
Stomata
Definition
Porelike openings in the underside of the leaf that allow carbon dioxide and oxygen to diffuse into and out of the leaf.
