A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.Nucleoside = Sugar + Base. Nucleotide = Sugar + Base + Phosphate.ugar + Base. A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. When phosphate group of nucleotide is removed by hydrolysis, the structure remaining is nucleoside. Sugar + Base + Phosphate.
RNA is single stranded,rna has uracil instead of thymine, rna has ribose sugar while dna has deoxyribose,rna is found everywhere in the cell and dna is only in the nucleus. Name three differences between dna & rna. helicase-the enzyme-unzips the two strands of a dna molecule at the hydrogen bonds between the paired nitrogen bases. what is the first step of dna replication and what enzyme is involved in this step.
