Active Site
the region of an enzyme's surface to which a specific set of substrates bind
alternate forms of the same gene
the condition of having an abnormal number of chromosomes
any eukaryotic chromosome that is not a sex chromosome; present in the smae number and kind in both males and females of the species
Codominant Inheritance
when two alleles act in unison to create a trait or characteristic, neither dominant over the other; both alleles are expressed
a typre of carbohydrate formed by two simple sugars bonded covalenly
Down Syndrome
condition in which an individual has three sets of the chromosome numer 21; sumptoms include mental retardation, short stature, larger than normal tongue and forehead
type of protein known as a biological catalyst because it speeds up chemical reaction by lowering the amount of activation energy needed for the reaction

Hair Root
the part of the hair below the epidermis
Hair Shaft
the part of the hair above the epidermis
a picture of an individual's chromosomes taken with the help of a microscope when the cell is actively dividing
Lock-and-Key Theory of Enzyme Function
the theory that an enzyme fits into a substrate site like a lock into a key as the result of the respective shape of the enzyme and the specific substrate site at with it is to operate

a type of carbohydrate formed by linking many monosaccarides to form a long chain ex/ glycogen, starch, and cellulose
a chain of amino acids joined by peptide bonds; ex/ (structual) keratin and collagen, (functional) enzymes
a molecule broken down or otherwise operated on by an enzyme
Turner's Syndrome
a condition in which a female has only one X for the sex chromosomes; symptoms include short stature, webbed neck, and reproductive sterility
XYY "Super" Male
a male with an extra Y chromosome; symptoms include tall stature and higher than average testosterone production
Control Test
a test of a system that includes all of the same features as the experimant system, except for the feature of being tested/studied; a test run that acts as a comparison
