What are the components of a nucleotide?
What are the Pyrimidine Bases? Which 2 are used in DNA? RNA?
What are the Purine bases?
Tumor supressor which prevents the cell from transitioning
into S phase from G1 Rb
Ability of cancer cells to invade the blood stream and move
from one location to another Metastasis
Structural identity gene in animals Hox gene
Gene responsible for yeast
1) In lactose induction, lactose binds to the lac I repressor protein
causing the confirmation of the repressor to change and function of
binding to operator is lost. Therefore, RNA Polymerase can bind to the
promoter and there will be frequent transcript
1) A higher (G-C) concentration in DNA from a mutation. More numerous strong bonds. More saturated
fatty acids in their membranes to have a higher melting point in membranes.
2) Ionic bonds may be affected by this acidic environment. Acid may destroy prot

Photosynthesis - Light Reactions
The light reactions of photosynthesis involve the use light energy to move electrons
through an electron transport chain (ETC) located in the thylakoid membranes inside
