What is the primary structure of nucleic acids? - answer Order of bases in
the polynucleotide sequence
What is the secondary structure of nucleic acids? - answer 3-D
conformation of the backbone
What is the tertiary structure of nucleic acids? - answer Supercoiling of
the molecule
What are the two types of nucleic acids? - answer RNA and DNA
What is a ribosome? - answer The sites of protein synthesis in all
organisms, consisting of RNA and protein
What is the monomer of nucleic acid? - answer Nucleotides
What are the components of nucleotides? - answer - Nitrogenous base
- A sugar

How are the components of a nucleotide connected? - answer Covalent
bonds
What are nucleotides? - answer Purine or pyrimidine bases bonded to
sugars which in turn are bonded to phosphate groups
, What are nucleic acid bases? - answer Nitrogen-containing aromatic
compounds that make up the coding portion of nucleic acids
What are pyrimidine bases? - answer Nitrogen-containing aromatic
compounds that contain a six-membered ring
What are purine bases? - answer Nitrogen-containing compounds that
contain a six membered ring fused to a five membered ring
What are the primidine bases? - answer - cytosine
- thymine
- uracil
What is unique about cytosine? - answer It is present in both DNA and RNA
What are the purine bases? - answer adenine and guanine
What is unique about the purine bases? - answer They are present in both
DNA and RNA
In a nucleoside, how does the base connect with the sugar? - answer
Glycosidic linkages
What is a ribonucleoside? - answer A compound formed when a
nucleobase forms a glycosidic bond with ribose
What is deoxyribonucleoside? - answer A compound formed when a
nucleobase and deoxyribose for a glycosidic bond
Where does the glycosidic linkage occur in pyrimidines? - answer From the
C-1' carbon of the sugar to the N-1 nitrogen on the base
