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- .
RNA or Ribonucleic Acid is made up of sugars and phosphates as well as nucleotides, Adenine, Cytosine, Guanine and Uracil.(which takes the place of Thymine in DNA) The nucleotides connect up to the other ones in DNA which has been split apart by enzymes then it makes up an amino acid chain called a poly peptide.
