Biology Test 2

loading
the force of attraction between unlike molecules
adhesion
the binding together of alike molecules
cohesion
bond, sharing electrons, unequal
polar covalent bond
bond, sharing electrons, equal
nonpolar covalent bond
bond between polar molecules
hydrogen bond
bond, sharing of electrons
covalent bond
bond, transfer of electrons
ionic bond
elongated molecules in which the secondary structure forms the dominant structure, have regular repeating structure [Protein]
fibrous
spherodial molecules, have tertiary or quaternary structure, soluble in water [Protein]
globular
complex structure forms by the interaction of 2 or more polypeptide chains
quaternary structure
the coiling or bending of the polypeptide into sheets, can exist separately or jointly in a protein
secondary structure
the folding back of a molecule upon itself and held together by disulfide bridges and hydrogen bonds, adding to proteins stability
tertiary structure
sequence of one chain of amino acids in the protein
primary structure
a chemical group that is attached to a core part of the molecule called "main chain" or backbone in proteins
"R" groups
result of reduction, used as a reducing agent to donate electrons
NADH
oxidizing agent which accepts elections from other molecules and becomes reduced
NAD+
makes up the backbone of each helical strand of DNA
phosphodiester linkage
THYMINE (DNA) = ??? (RNA)
uracil
base for THYMINE and CYTOSINE
pyrimidine
base for ADENINE and GUANINE
purine
the sugar component in the side chains of DNA
deoxyribose
