Nucleic Acids, Nucleotides, DNA, RNA

Base

Guanine (G)

R = H

deoxyguanosine triphosphate

R = OH

guanosine 5’-monophosphate

Base

Cytosine (C)

R = H

deoxycytidine triphosphate

R = OH

cytidine 5’-monophosphate

Base

Adenine (A)

R = H

deoxyadenosine triphosphate

R = OH

adenosine 5’-monophosphate

Base

Thymine (T)

R = H

deoxythymidine triphosphate

Base only present in DNA instead Uracil.

Base

Uracil (U)

Base only present in RNA instead of Thymine.

R = OH

uridine 5’-monophosphate

DNA is built from R = H nucleotides, RNA is built from R = OH nucleotides
