If your baby is very young the cold may linger for up to two weeks. Your baby will have from between six to 10 colds by the time he is two years old. 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.
All nucleotides are composed of three parts: a five-carbon sugar, a phosphate, and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose, which is found in ribonucleotides and RNA, or deoxyribose, which is found in deoxyribonucleotides and DNA. The only difference between these two sugars is that deoxyribose has one fewer oxygen atom than ribose. The five carbon atoms in the sugar are numbered sequentially.
