DNA, RNA, and Protein Flashcards Preview

q
What biological role is played by nucleic acids?
a
Nucleic acids store genetic material in the form of DNA, allowing it
to be inherited. They also direct the formation of protein through
translation from mRNA transcripts.
Nucleic acids include DNA, or deoxyribonucleic acid, and RNA, or
ribonucleic acid.
2
q
Define:
nitrogenous base
a
,Nitrogenous bases are molecules that serve as main components
of DNA and RNA. As their name implies, all contain nitrogen and
display basic properties.
The nitrogenous bases used in normal nucleic acids are guanine, cytosine,
adenine, thymine, and uracil.
3
,q
Define:
nucleotide
a
A nucleotide is a molecule that consists of a nitrogenous base, a
sugar, and at least one phosphate group.
, The nucleotides that function as nucleic acid subunits contain only a single
phosphate, but others, such as ATP, have several.
4
q
How does a nucleoside differ from a nucleotide?
