Structure of DNA and RNA Flashcards
1
Q
DNA, what is it’s role?
A
carry genetic code
and instructions for making protiens
2
Q
3 components of all nucleotides
A
a pentose sugar
a phosphate
a nitrogenous base
3
Q
Draw a nucleotide
A
Phosphate = circle
right, down
sugar deoxyribose/ribose = pentagon
up
base = rectangle
4

RNA and DNA - what are they made out of?
A
ribose/deoxyribose
phosphate group and organic base

double helix
2 polynucleotide chains
hydrogen bonds between specific complementry base pairs.
6
