Starting at 6 months, let kids occasionally drink from a sippy cup, so when you eventually do get rid of the bottle, your child will already be acquainted with the cup, suggests Corrigan. Let babies get used to a cup while they're in the tub. They can pour water out of it, drink from it, or even make a mess with it.
Answer: Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: 1  Nitrogenous Base. 2  Purines and pyrimidines are the two categories of nitrogenous bases. 3  Pentose Sugar. 4  In DNA, the sugar is 2'-deoxyribose. 5  Phosphate Group. 6  A single phosphate group is PO 4 3- .
Report Abuse. DNA and RNA are polymers made of monomeric subunits, called nucleotides, which can be linked together in any order. The nucleotide is the basic, repeated unit of DNA or RNA strand and contains a nitrogenous base-a double-ring purine or a single-ring pyrimidine, linked to phosphorylated sugar.The sugar with an attached base, but without a phosphate group is called a nucleoside.n DNA molecule, the sugar is 2â²-deoxyribose and in RNA molecule-ribose. The sugars comprise the backbone of every DNA or RNA chain, linked by covalent phosphodiester bond between 5â²- and 3â²-carbons of two adjacent sugars.
