Deoxycytidine triphosphate (dCTP) is one of four building blocks of nucleic acid DNA . It consists of a deoxyribose , the base cytosine and a triphosphate group.
biosynthesis
The deoxyribonucleoside triphosphates are synthesized in the cell as high-energy compounds from 2'-deoxyribonucleotide-5'-monophosphate, through two successive phosphorylation steps with ATP as a phosphate group donor.
function
dCTP is one of the four building blocks of DNA . When it attaches to the DNA strand, pyrophosphate is split off. The genetic code of DNA results from the sequence of the bases of these building blocks. Since the base of dCTP is cytosine , this building block encodes the C of this code.
