RNA- ribose -phosphate group- adenine, guanine, cytosine, uracil
What are the four major differences btw DNA and RNA? - ans1. 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? - ansThe uprights are the sugar
phosphate backbone, and the rungs are the bases.
Explain the 2 differences btw hydrolysis and dehydration condensation. - ansDuring
dehydration condensation biomacromolecules are synthesized by joining building block
monomers. A water molecule is lost and energy is used.
Biomacromolecules are broken down into monomers during hydrolysis when a water
molecule is added and energy is released.

animals

explain the use of each.
Triglyceride - ansLipid; the major form of fuel storage that when broken down produces

Why are proteins so often used to build structures? - ansBecause they are "structurally
sophisticated". They are strong, yet flexible and incredibly diverse.
Explain the following terms in regard to proteins:
a. Primary structure:
b. Secondary structure:
c. Tertiary structure:
d. Quaternary structure: - ansa. Amino acid monomers in a linear chain

possible that one chain can have both patterns

triglycerides)
Explain the 3 differences b/t prokaryotic and eukaryotic cells. - ans1. Prokaryotic cells are
typically smaller than eukaryotic cells. Most are between 1-10 micrometers in size (about
1/30,000 of an inch)
2. The DNA of a prokaryotic cell is not enclosed in a nuclear membrane (prokaryotic means
"before the nucleus"), whereas Eukaryotic cells possess a nucleus 3. Prokarytic cells do not
contain many of the internal membrane-bounded organelles of eukaryotic cells
