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.
The four different nitrogenous bases; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are the parts that are different on different nucleotides. These bases differ in â¦ their chemical structure: The pyrimidines, Cytosine and Thymine have one ring (with different side chains).NA (Deoxy ribo-nucleic acid) is made up of structures known as nucleotides, there are four nucleotides from which all the DNA coding has been written, which are as follow : adenine (a purine). cytosine (a pyrimidine). guanine (a purine).
