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- .
Confidence votes 7.7K. Nucleotides. Both DNA and RNA are nucleic acids, and are polymers of nucleotides. A nucleotide has three components: a pentose (five-carbon sugar), and attached to different parts of it a phosphate group and a nitrogenous base (either a purine or a pyrimidine).NA and RNA are polymers consisting of monomres called nucleotides, which are composed of a sugar (deoxyribose for DNA and ribose for RNA), a phosphate group, and a nitrogeno â¦ us base (Adenine, Thymine, Cytosine, and Guanine for DNA, and Adenine, Uracil, Cytosine and Guanine for RNA).
