Review Of Nucleic Acid Structure Flashcards
1
Q
What does DNA stand for?
A
Deoxyribonucleic acid
2
Q
What does RNA stand for?
A
Ribonucleic acid
3
Q
What is only found in DNA?
A
- Thymine
- 2-Deoxyribose Sugar
4
Q
What is found in both DNA and RNA?
A
- Adenine
- Guanine
- Cytosine
- Phosphate
5
Q
What is only found in RNA?
A
- Uracil
- Ribose Sugar
6
Q
Purines
A
- Double ringed
- Adenine
- Guanine
7
Q
Pyrimidines
A
- Single ringed
- Cytosine
- Uracil
- Thymine
8
Q
What is a nucleotide made up of?
A
- A phosphate
- A sugar
- A nitrogenous base
9
Q
What is a nucleotide?
A
The smallest subunit of either DNA or RNA
10
Q
What are the two different base pairs?
A
- Adenine and thymine (or uracil)
- Guanine and Cytosine
11
Q
What base pair has a higher chance of mutations?
A
- Adenine and thymine
- Because they only have 2 hydrogen bonds so they are easier to break
12
Q
Five Prime End
A
Called this cuz the phosphate is the functional group at the end of that strand and is attached to Carbon #5 of the sugar
13
Q
Three Prime End
A
Called this cuz the hydroxyl functional group is at the end of that strand and is attached to Carbon #3 of the sugar
14
Q
What are phosphodiester links?
A
- Bonds that form between the sugar and phosphate
- Forms the backbone of nucleic acids
