The Nature of Matter
The basic unit of matter
What is an atom?
Chemical composition of water.
What is H2O (2 hydrogens and 1 oxygen)?
Macromolecule whose subunits are monosaccharides (i.e. glucose).
What is carbohydrates?
The process that changes one set of molecules into another set of molecules.
What is chemical reaction?
Method to measure how much a substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution
What is spectrophotometry?
Bond formed when oppositely charged ions are attracted to each other
What is an ionic bond?
Partial charge of oxygen atom in water due to unequal sharing of electrons?
What is negative?
Macromolecule that stores and transmits genetic information.
What is nucleic acid?
Energy needed to get a reaction started.
What is activation energy?
Laboratory practices and procedures designed reduce the contamination from microbes
What is aseptic technique?
Strong bond formed when electrons are shared by atoms
What is a covalent bond?
Partial charge of hydrogen atom in water due to unequal sharing of electrons
What is positive?
Monomer of nucleic acid.
Speeds up the rate of a chemical reactions in living things.
What is enzyme (catalyst)?
Technique used to separate DNA based on size
What is agarose gel electrophoresis?
What is 20?
What is hydrogen bond?
Group that differs among 20 amino acids
What is side chain (R-group)?
Area of enzyme where substrates bind
What is active site?
Technique in which bacteria are hijacked by DNA (plasmid) introduced by scientist
What is bacterial transformation?
Strongest chemical bond
What is covalent?
A molecules that has uneven distribution of charge across their geometry resulting in one side being positive and the other side negative
What is polar?
Four levels of protein structure.
What is primary, secondary, tertiary and quaternary?
Effect of enzymes on activation energy of chemical reaction
What is lower?
Biotech's greatest freshmen
Who is......all of you!!!!
