What are the particular types of each of these that are found in DNA and what are the corresponding types that are found in RNA? - ANSWER-a. sugar, phosphate group, nitrogenous base b. DNA- deoxyribose- phosphate group- adenine, guanine, cytosine, thymine RNA- ribose -phosphate group- adenine, guanine, cytosine, uracil What are the four major differences btw DNA and RNA? - ANSWER-1. DNA contains deoxyribose - RNA is ribose 2. DNA: thymine RNA: uracil 3. DNA: double stranded helix RNA: single strand DNA is often described as a coiled ladder. In this description, what two parts of a DNA nucleotide form the uprights? What part forms the rungs? - ANSWER-The uprights are the sugar phosphate backbone, and the rungs are the bases. Explain the 2 differences btw hydrolysis and dehydration condensation. - ANSWER-During dehydration condensation biomacromolecules are sy
