STATE UNIVERSITY EXAM WITH 100%
CORRECT ANSWERS 2025
conservation correct answers >> describes biochemistry
across many life forms
macromolecules correct answers >> large polymers
monomers correct answers >> repeating units in
macromolecules linked together by covalent bonds
DNA correct answers >> composed of four chemical units
called nucleotide bases; adenine, guanine, cytosine, and thymine
nucleotide bases correct answers >> chemical units;
adenine, cytosine, guanine, thymine
RNA correct answers >> built from nucleotide bases similar
to DNA
Proteins correct answers >> built from amino acids
Carbohydrates correct answers >> built from
monosaccharides
Lipids correct answers >> built from fatty acids
, DNA replication correct answers >> structure shows function;
if separated into two single strands, each strand can act as a
template for the generation of its partner strand
DNA double helix correct answers >> composed of two
intertwine strands arranged such that the sugar-phosphate
backbone lies on the outside and the bases on the inside;
antiparallel polymers (strands)
Polymer directionality correct answers >> sugars are all
oriented the same way, so each strand will have one end
distinguishable from the other
covalent bonds correct answers >> sharing of a pair of
electrons between adjacent atoms; such as the bone that hold the
atoms together within the individual bases of DNA
non covalent bonds correct answers >> four fundamental
types; weaker than covalent bonds; ionic (electrostatic)
interactions, hydrogen bonds, van der Waals interactions, and
hydrophobic interactions
hydrogen bonds correct answers >> involve hydrogen atoms
that interact with an electronegative atom; holds water molecules
together
hydrogen bond donor correct answers >> the group that
includes both the atom to which the hydrogen atom is more
tightly linked and the hydrogen atom itself
