Deoxyribose Nucleic acid Ribonucleic acid |
|
Nucleotides
|
Make up Nucleic acids
Consist of; A pentose sugar A phosphate An organic base |
|
The five different bases in Nucleic acids
|
Guanine
Adenine Thymine Cytosine Uracil |
|
Nucleotides link together to form a chain
|
Condensation. Covalent bonds form between the phosphate and the sugar. Sugar phosphate backbone.
|
|
DNA double helix structure
|
A single strand of nucleotides is switched upside down, and another strand fits in with its complimentary base pair. Hydrogen bonds form between the two bases, and this causes the structure to twist because one base is always shorter than the other.
