100
what is the most important biological molecule?
Carbon 
100
what is the monomer of proteins 
amino acids 
100
name two types of nucleic acids 
RNA and DNA
100
Repeating units are simple sugars called 
monosaccharides 
200
Name one of 3 modern cell biology approaches 
Cytology, Biochemistry, Genetics 
200
what type of bonding is in carbon molecules? 
covalent 
200
what are the chemical properties of amino acids determined by? 
R Group 
200
name the purines and pyrimidines 
Guanine and Adenine


Cytosine, Thymine(DNA), and Uracil (RNA)

200
How many sugars are in, Triose, Hexose, Pentose? 
3,6,5 
300
In the cell, what do you measure using Micrometers?
Cells and unicells organisms 
300
what is a hydrocarbon? 
a molecule that only consist of carbon and hydrogens 
300
why are proteins directional? 
because the chain goes from N terminus to C terminus, and you can only add to the C terminus side. 
300
what is the difference between nucleotide and nucleoside
Nucleotide= base, sugar, and phosphate

Nucleoside= base and sugar 

300
what are the two forms of glucose? and what does it depend on? 
alpha-D glucose 

Beta-D glucose

this depends on the OH group on the C1 

400
what is chromatogrpahy? 
technique used to separate molecules from a solution, based on size, charge, or affinity
400
what is the strongest bond enegery out of these three? 

C-C, C-H, C-N 

C-H
400
what are higher levels of proteins structures dictated by? 
primary structure. 
400
How many hydrogen bonds do A and T have? how many hydrogen bonds do G and C have?
A-T=2

G-C= 3

400
what does the condensation reaction result in? 
glycosidic bond 
500
what is an example that we use to measure in nanometers, in the cells?
Membrane, microtubules, microfilament, ribosomes. 
500
why is water polar? 
because of the unequal distribution of the charges. 
500
give one example of fibrous and globular proteins 
Keratin

tobacco 

500
what is the DNA backbone composed of? and what are the characteristics of it?
Sugars and phosphates 

The DNA helix must be antiparallel and complementary
