Chapter 5 - Nucleic Acids Flashcards
1
Q
There are two different types of Nucleic acids, what are they?
A
Deoxyribonucleic Acid (DNA) Ribonucleic Acid (RNA)
2
Q
What are Nucleic Acids?
A
They are macromolecules that exist as polymers called polynucleotides
3
Q
What are the 5 different nitrogenous bases and how to they connect with each other in a DNA coding?
A
Cytosine (C) Thymine (T) Uracil (U, only in RNA) Guanine (G) Adenine (A)
G-C
T-A (U will be substituted with T in a RNA coding)
4
Q
Which are the pyramid ones of the Nitrogenous bases?
A
Thymine
Cytosine
Uracil
5
Q
Which are the purines in the nitrogenous bases?
A
Adenine and guanine
6
Q
What is the structure of a DNA?
A
- Forms a double helix
- two sugar phosphate backbones
- 5’ to 3’ (five prime to three prime)
- antiparallel
- adenine to thymine
- guanine to cytosine
7
Q
What is the structure of RNA?
A
Single stranded
Has uracil instead of thymine
Ribose in backbone instead of deoxyribose
May Bond to itself
8
Q
Define nucleotides and polynucleotides.
A
Nucleotide is a monomer for Nucleic acids
Polynucleotides is a polymer for Nucleic acids.
