The reactant on which an enzyme works.

any malignant growth or tumor caused by abnormal and uncontrolled cell division

series of events that cells go through as they grow and divide

A complex molecule containing the genetic information that makes up the chromosomes.

The process in which DNA makes a duplicate copy of itself.

cell division in which the nucleus divides into nuclei containing the same number of chromosomes

monomers of proteins

A specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid

A type of RNA, synthesized from DNA, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein.
