Hvad er de fire typer nukleotider DNA?

DNA består af fire typer nukleotider, der hver består af:

1. deoxyribosesukker: Et fem-carbon-sukkermolekyle.

2. phosphatgruppe: Et molekyle indeholdende fosfor.

3. nitrogenisk base: En af fire mulige molekyler:

* adenin (a) :En purinbase.

* guanine (g) :En purinbase.

* cytosin (c) :En pyrimidinbase.

* thymin (t) :En pyrimidinbase.

Så de fire typer nukleotider i DNA er:

* deoxyadenosinmonophosphat (DAMP) :Adenin + deoxyribose + phosphat

* deoxyguanosinmonophosphat (DGMP) :Guanine + deoxyribose + phosphat

* deoxycytidinmonophosphat (DCMP) :Cytosin + deoxyribose + fosfat

* deoxythymidinmonophosphat (DTMP) :Thymin + deoxyribose + phosphat
