All the definitions you need can be found below:
amino acids - Nitrogen-containing molecules. The "building blocks" of proteins.
bacteriophage - A virus which infects a bacterium.
chromosome - A linear arrangement of genes and other DNA, sometimes associated with protein and RNA.
developmental noise - Random events in an organism's development which cause a variation in its eventual phenotype.
DNA - Deoxyribosenucleic acid. The genetic material. It consists of two polynucleotide chains, each forming a right-handed helical spiral, which coil around one another to form a double helix. The molecule carries the genetic code as a sequence of bases along its length and is capable of accurate replication.
enzyme - A protein which functions as a biological catalyst.
gamete - Specialised haploid cell which forms the zygote by fusion with a gamete from the opposite sex or mating type.
gene - The fundamental unit of heredity. A functional region of a DNA molecule containing the genetic code for the production of a specific protein. Consists of a transcribed region and a regulatory sequence.
gene therapy - Correction of a genetic defect by the insertion of new DNA into the genome.
genome - An organism's complete complement of genetic material.
genotype - The inherited genetic code of an organism.
linkage - The association of genes on the same chromosome.
organism - Any individual living creature.
phenotype - An organism's morphology, physiology, behaviour, and ecological relationships.
progeny - Offspring.
protein - A chain of amino acids joined by peptide bonds. May consist of more than one polypeptide chain.
restriction enzyme - An enzyme which "cuts" DNA molecules, often at precise regions.
RNA - Ribonucleic acid. Single-stranded
nucleic acid similar to DNA, but possessing ribose instead of deoxyribose
sugar units, and uracil instead of thymine.
