A phosphate group bonded covalently to a sugar molecule.
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules.
Alternating deoxyribose and phosphate molecules.
What makes up a DNA strand
The phosphate groups and deoxyribose molecules makes up the DNA ladder.
Phosphate and sugar make up the sides of a DNA ladder.
Sugar molecules and phosphate groups
alternating deoxyribose sugar molecules and phophate groups
They are phosphate and deoxyribose (sugar)
Nucleic acids.
The sides of the DNA latter consist of the sugar deoxyribose and phosphates. The bond between the latter and the nitrogen bases together is known a a nucleotide. Nucleotides are molecules that make up the structure of DNA and RNA.
