cancer
any malignant growth or tumor caused by abnormal and uncontrolled cell division
density-dependent inhibition
The phenomenon observed in normal animal cells that causes them to stop dividing
when they come into contact with one another.
null hypothesis
the hypothesis that there is no significant difference between specified populations,
any observed difference being due to sampling or experimental error.
experimental hypothesis
predicts the relationship between the IV and the DV
anchorage dependent inhibition
A mechanism that controls cell growth in which cells can only divide when they
are anchored to a surface; i.e. inside a culture jar or extracellular matrix of a tissue
chromosome
A threadlike, gene-carrying structure found in the nucleus. Each chromosome
consists of one very long DNA molecule and associated proteins.
amino acids
building blocks of proteins
amphipathic
, having both a hydrophilic region and a hydrophobic region
carbohydrate
compound made up of carbon, hydrogen, and oxygen atoms; major source of
energy for the human body
denature
A change in the shape of a protein (such as an enzyme) that can be caused by
changes in temperature or pH (among other things).
hydrogen bond
weak attraction between a hydrogen atom and another atom
ion
A charged atom
lipid
macromolecule made mostly from carbon and hydrogen atoms; includes fats, oils,
and waxes
macromolecule
A very large organic molecule composed of many smaller molecules
monomer
small chemical unit that makes up a polymer
monosaccharides
Single sugar molecules
non-polar molecule
molecule that shares electrons equally and does not have oppositely charged ends;
hydrophobic
nucleic acid
a complex organic substance present in living cells, especially DNA or RNA,
whose molecules consist of many nucleotides linked in a long chain.
nucleotide
