2026
(C) Carboxyl terminus - CORRECT ANSWER - Exposed carboxyl
group
(GDP + Pi) + RAS - CORRECT ANSWER - Inactive
(N) (Amine) terminus - CORRECT ANSWER - Where the amino
acid chain begins
1 in 2 men are likely to get what? - CORRECT ANSWER - Some
type of cancer
1 in 3 women are likely to get what? - CORRECT ANSWER -
Some type of cancer
3D microscopy - CORRECT ANSWER - Compiling the images
from numerous focal planes allows for the 3D constrction of
structures
,Acetyl on Lys - CORRECT ANSWER - Helps to create histone
code in chromatin
Acidic amino acids - CORRECT ANSWER - Aspartic acid and
Glutamic acid
Affinity - CORRECT ANSWER - How strong one molecule binds
to another
Alpha helices - CORRECT ANSWER - Spiraling single
polypeptide chains
Amino acids --> - CORRECT ANSWER - Proteins
Antibodies - CORRECT ANSWER - Proteins utilized by the
immune system to identify and neutralize foreign agents
Antigens - CORRECT ANSWER - Foreign material that invades
the body
Are antibodies specific? - CORRECT ANSWER - YES
,Are domains specific to one protein? - CORRECT ANSWER -
No
ATPase - CORRECT ANSWER - Enzyme that catalyzes
hydrolysis of ATP
Backbones of proteins - CORRECT ANSWER - Polypeptides
Basic amino acids - CORRECT ANSWER - Histidine, Lysine,
Arginine
Biochemistry study of cell bio - CORRECT ANSWER -
Molecular and structural biology
Break it - CORRECT ANSWER - Destroy/hydrolyze
Brightfield microscope - CORRECT ANSWER - A microscope
that allows light rays to pass
Cancer is what type of disease? - CORRECT ANSWER - Genetic
, Cell division - CORRECT ANSWER - Prophase, interphase,
metaphase, telophase, cytokinesis
Cell lysate - CORRECT ANSWER - Fluid containing the contents
of lysed cells
Central Dogma - CORRECT ANSWER - DNA -> RNA -> Protein
Chemical properties of proteins - CORRECT ANSWER - The
beauty of these two structural elements is that their stability is
dependent only upon hydrogen bonding between peptide
bonds, so even wildly divergent polypeptide sequences can
ultimately arrange themselves into similar protein structures
Coimmunoprecipitation - CORRECT ANSWER - Purification,
through antibody binding, of specific proteins bound to other
proteins or nucleic acids
Common Ras mutation - CORRECT ANSWER - G12C, G13V,
