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- .
The monomers of both DNA and RNA are composed of three parts: a phosphate group, a pentose (5-carbon sugar), and a nitrogenous base. Both DNA and RNA use a form of ribose as their sugar (RNA uses ribose itself; in DNA, a single oxygen atom has been removed from the 2' carbon of ribose, to form deoxyribose).Both DNA and RNA use the bases adenine, cytosine, and guanine.Both DNA and RNA undergo complementary base pairing (DNA usually between two different strands, and RNA usually between two regions of a single strand). Both DNA and RNA are synthesized in the 5' to 3' direction.oth DNA and RNA use the bases adenine, cytosine, and guanine. Both DNA and RNA undergo complementary base pairing (DNA usually between two different strands, and RNA usually between two regions of a single strand).
