And each cold is just as hard on you and your baby as the first one.If your baby is under three months old when he gets his cold you should contact your doctor.
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.
Nucleotides are the subunit that is polymerized (connected into a long chain) to make nucleic acids (DNA and RNA). Nucleotides consist of three smaller components: a ribose sugar, a nitrogenous base, and phosphate group(s). Generic nucleotide structure. The connection that forms between nucleotides is between the sugar of the first nucleotide and the phosphate group of the second. 2  Each connection between nucleotides is a covalent bond, so the nucleic acids have a covalently attached sugar-phosphate backbone.
