Dihydrogen Monoxide Atkins would not approve The Big Groups DNA Replication

100

What are carbon, hydrogen, nitrogen, and oxygen
The four most frequently occurring elements in living things

100

What is Glucose (G6 :-)
A six carbon monosaccharide used as source of chemical energy for living organisms; Hint: Far East Movement claims to be fly like this.

100

What are fatty acids and amino acids (hmmm...what do these terms have in common?)
Two molecules that we studied that have a carboxylic acid group in the monomer structure.

100

What are phosphate, deoxyribose, nitrogenous base
The three molecules that make up a DNA nucleotide

100

What is 5' to 3'
New strands of nucleic acids (DNA and RNA) can only be made in this direction.

200

What is sulphur, phosphorous, iron, sodium, and calcium
The five other key elements (according to IBO) that are needed by living organisms.

200

What are sucrose, maltose, and lactose
Three disaccharides

200

What is peptide
The type of bond that connects two amino acids in a dipeptide

200

What is cytosine
In complementary base pairing, this is the base that guanine always pairs with.

200

What is helicase
This enzyme is responsible for unwinding the double helix and separating the two template strands by breaking the hydrogen bonds between the bases...otherwise known as unzipping your genes :-)

300

What is polar covalent
What type of bond connects the hydrogen atoms to the oxygen atom in a water molecule?

300

What is hydrolysis
Starches are broken down into disaccharides through this process. Hint: Water is required!

300

What is glycerol
The molecule that fatty acids connect with to form a triglyceride.

300

What is covalent
This type of bond connects nucleotides in a single strand

300

What is primase
This enzyme come after helicase and lays down RNA nucleotides to start the new strand.

400

What is hydrogen bonding
The high boiling point of water, surface tension, cohesion and adhesion are all a result of this intermolecular force.

400

What are maltose and water
The condensation of two molecules of glucose will produce these two molecules

400

What is lipids
This type of molecule is used for energy storage, thermal insulation, and buoyancy

400

What is 5'
In a nucleotide this is the carbon that the phosphate is connected to.

400

What is ligase
This enzyme forms covalent, phosphodiester bonds to connect the Okazaki fragments formed on the lagging strand.

500

What is solvent
Water is a good transport medium because of these properties

500

What are glycogen and liver
Excess glucose is converted into this in mammals and stored in this organ (name the molecule and the organ)

500

What are lipids
In terms of energy storage, these molecule are insoluble (bad for transport), but gives you more bang for your buck...in fact it holds twice as much energy per GRAM than it's main energy-yielding competitor!

500

What is Adenine and Guanine (PU AG!)
These are the DNA nucleotides that are purines

500

What is deoxyribose III and 3'
This enzyme adds new nucleotides to the growing strand by helping to form a covalent bond between the phosphate of the new nucleotide and this exposed carbon on the growing strand. (you need to name the enzyme and the carbon)
