Guide Questions:Q 32. What are the common parts of a nucleotide?Q 33. What is the one part of the nucleotide that differs among the otherdifferent nucleotides?Q 34. List the different kinds of nitrogen bases.A molecule of deoxyribose joins with phosphate and anyone of the four basesto form a chemical compound called a nucleotide. A nucleotide is named for the basethat joins with the deoxyribose. For example, if thymine attaches to deoxyribose, themolecule is called a thymine nucleotide.3. Complete the right side of the DNA molecule by matching the bases of the othernucleotides. It may be necessary to tum molecules upside down in order tomake them fit.Guide Questions:Q 35. What is the pairing arrangement of the nitrogenous bases?pairs withandpairs withQ 36. Are there always going to be an equal number of adenine andthymine nucleotides in a molecule? Why?Q 37. Are there always going to be an equal number of guanine andcytosine nucleotides in a molecule? Why?
Answer (1)
32.the common parts are deoxyribose sugar,phosphate molecules and nitrogen bases33.nitrogen bases34.adenine,guanine,thymine and cytosine 35.adenine pair with thymine and guanine pair with cytosine36.yes,there is an equal number of adenine and thymine it because they are pair with each other37.yes.there is an equal number of guanine and cytosine it because they are pair with each other.38.the sides of the ladder are made up of alternating Sugar and phosphate molecules.the steps(or rungs) of the ladder are made up of nitrogen bases held together by hydrogen bonds
