DNA and RNA
RNA
-
-
Components of an RNA nucleotide:
- Ribose sugar
- Phosphate group
- One of the organic bases adenine, cytosine, guanine or uracil.
An RNA molecule is a relatively short, single polynucleotide chain
DNA

-
Components of a DNA nucleotide:
- Deoxyribose sugar
- Phosphate group
- One of the organic bases adenine,
cytosine, guanine or thymine.
A DNA molecule is a:
Double helix with two polynucleotide chains held together by hydrogen bonds between specific complementary base pairs
Nucleotides
Made from:
- pentose sugar (5 C atoms)
- nitrogen-containing base
- phosphate group
