3.8 Nucleic Acids Flashcards
1
Q
Nucleic acid
A
Large molecules discovered in cell nuclei. Two types, DNA and RNA and both have roles in the storage and transfer of genetic information and protein synthesis
2
Q
Nucleotide
A
Made of 3 components, sugar, phosphate group & nitrogenous base.
3
Q
Phosphodiester bonds
A
Bonds created to link phosphate geoup and pentose sugar of two nucleotides
4
Q
Hydrolysis
A
Reverse of condensation reaction
5
Q
Pyrimidine
A
Smaller bases, contain single carbon ring structure- Thymine and Cytosine
6
Q
Purine
A
Larger bases, contain double carbon ring structures- Adenine and Guanine
7
Q
Complementary base pairing
A
Connection of nucleotides. Adenine and thymine form two hydrogen bonds. Cytosine and guanine form 3 hydrogen bonds.
