DNA
|
Deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.
|
|
Adhesion
|
The clinging of one substance to another.
|
|
Cardohydrate
|
Sugars and starches, which provide energy for humans and animals, and cellulose which make up many plant structures.
|
|
Chitn
|
A polysaccharide that is the principal component of the exoskeletons of arthropods and of the bodies of fungi.
|
|
Cohesion
|
The stinking together of like molecules, such as water molecules.
|
|
Compound
|
A chemical substance consisting of two or more different elements.
|
|
Condensation Reaction
|
A chemical reaction in which two molecules form a new molecule and condensation.
|
|
Controlled Experiment
|
An experiment in which tests a hypothesis by looking for changes brought on by alterations to a variable. In a controlled experiment, an independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.
|
|
Covalent Bond
|
Bond in which one or more pairs of electrons are shared by two atoms.
|
|
Dehydration Synthesis
|
a chemical reaction that involves the loss of water from the reacting molecule.
|
|
Double Helix
|
A pair of parallel helices intertwined about a common axis.
|
|
Element
|
A substance that can't be broken down to a smaller substance by chemical reactions.
|
|
Genes
|
A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
|
|
Glycogen
|
A substance, only in animals, used as a store of carbohydrates.
|
|
Hydrolysis
|
The chemical breakdown of a compound due to reaction with water.
|
|
Ionic Bond
|
A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion.
|
|
Isomer
|
Each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties.
|
|
Amino Acid
|
A simple organic compound containing both a carboxyl and an amino group.
|
|
Monosaccharide
|
Any of the class of sugars that cannot be hydrolyzed to give a simpler sugar.
|
|
Peptide Bond
|
A peptide bond (amide bond) is a covalent chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amine group of the other molecule.
|
|
Polymer
|
A substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together.
|
|
Polypeptide
|
A linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule.
|
|
Primary Structure
|
The characteristic sequence of amino acids forming a protein or polypeptide chain, considered as the most basic element of its structure.
|
|
Protein
|
Any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms.
|
|
Ribose
|
AN organic compound found in nucleotides of RNA and in ATP.
