I'm unclear what you mean. Cysteine is an amino acid and never found in DNA. Do you mean cytosine? If you do, cytosine is not directly linked to phosphates - rather cytosine is linked to deoxyribose which in turn is linked to the phosphate group.
A nitrogenous base, a simple sugar, and a phosphate group.
The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
Deoxyribose and phosphate.
Sugar molecules and phosphate groups
Phosphate and sugar molecules
I belive that would be a Sugar-Phosphate.
The molecules of the sugar-phosphate backbone in DNA are joined together by covalent bonds (known as phosphodiester bonds).
A nitrogenous base, a simple sugar, and a phosphate group.
Deoxyribose And Phosphate
The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
The phosphate groups and deoxyribose molecules makes up the DNA ladder.
a deoxyribose sugar molecule, a phosphate group, and a nitrogen base
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
DNA is made up of deoxyribose sugar and phosphate molecules and four types of bases, namely, adenine, guanine, cytosine and thymine.
The phosphate and deoxyribose in the backbone of DNA are constant throughout the molecule.
