Which part of an amino acid is always acidic? - The carboxyl group (COOH) contains two
oxygen atoms that tend to pull electrons away from the hydrogen atom, so this group tends to
lose a proton and is acidic.
Which monomers make up RNA? - nucleotides
True or false? Enzymes in the digestive tract catalyze hydrolysis reactions. - True
Which of the following statements about the formation of polypeptides from amino acids is true?
A)The reaction occurs through the addition of a water molecule to the amino acids.
B)Polypeptides form by condensation or hydrolysis reactions.
C)A bond can form between any carbon and nitrogen atom in the two amino acids being joined.
,D)A bond forms between the carboxyl functional group of one amino acid and the amino
functional group of the other amino acid. - D)A bond forms between the carboxyl functional
group of one amino acid and the amino functional group of the other amino acid.
If a DNA double helix is 100 nucleotide pairs long and contains 25 adenine bases, how many
guanine bases does it contain? - 75
The two strands of a DNA double helix are held together by _____ that form between pairs of
nitrogenous bases. - HYDROGEN BONDS
A nucleotide is composed of a(n) _____. - phosphate group, a nitrogen-containing base, and a
five-carbon sugar
If 14C-labeled uracil is added to the growth medium of cells, what macromolecules will be
labeled? - RNA
Which of the following can be used to predict the 3-D structure of the protein? - sequence of
amino acids in the polypeptide chain
Tertiary structure is NOT directly dependent on _____. - peptide bonds
Radioactive decay is likely to happen when _____________? - an atom has too many neutrons.

C)Plants carry out cellular respiration only in organs such as roots that cannot carry out
photosynthesis. - A
The enzyme phosphofructokinase is allosterically regulated by ATPATP and related molecules.
