1.5.1 DNA and RNA Flashcards
1
Q
What is a nucleotide made from?
A
- Deoxyribose sugar
- Phosphate
- Nitrogenous base
2
Q
What bonds link nucleotides?
A
Phosphodiester
3
Q
Why is DNA in a double helix structure?
A
Hydrogen bonds between complementary base pairs. Adenine and thymine form 2 hydrogen bonds. Cytosine and guanine form 3 hydrogen bonds
4
Q
Why is DNA stable?
A
Sugar phosphate backbone and double helix
5
Q
Why is DNA double stranded?
A
So replication occurs and each strand can act as a template
6
Q
Why does DNA have weak H bonds?
A
Easy strand separation during replication
7
Q
Why is DNA large?
A
To carry lots of information
8
Q
Why does DNA have complementary base pairing?
A
Allows identical copies to be made
9
Q
What is RNA made out of?
A
Ribose
Nitrogenous base
Phosphate
