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- .
Sugar Backbones. DNA and RNA are made up of subunits called nucleotides. All nucleotides have a sugar backbone, a phosphate group, and a nitrogenous base. Both DNA and RNA have sugar âbackbonesâ that are made up of five carbon molecules. However, they are different sugars that make them up. DNA is made up of deoxyribose and RNA is made up of ribose. Those sound pretty similar and their structures are very similar.
