| Code | the base sequence of a gene |
| Codon | three base sequences |
| Cytosine | Pairs with Guanine |
| Deoxyribonucleic acid (DNA) | A nucleic acid that consists of nucleotides and stores information |
| DNA probe | a short sequence of single stranded DNA |
| Erythropoietin (EPO) | hormone that regulates the production of red blood cells |
| Gene | A specific sequence of DNA. 3,000 Base pairs long. Instruction set for producing a particular molecule. Protein |
| Gene library | All the different fragments of original DNA |
| Gene therapy | designed to treat or cure a variety of different diseases by inserting a fuctional gene to replace the bad one. |
| Genetic engineering | the manipulation of organismsgenetic material by adding,deleting, or transplanting from one organism to another. |
| Genome | The full set of DNA present in an individual organism. |
| Genotype | genes that an organism carries for a particular trait. |
| Golden rice | Rice that is made with beta carotine which supplies people with Vitamin A |
| Guanine | Pairs with Cytosine |
| Human genome project | a project to decode the 3 billion base pairs in the human genome and to identify all the genes present in it. |
| Human growth hormone | Stimulates protein synthesis and growth to virtually every part of the Body |
| Hybridization | The way the gene of interest is found |
| Intron | Non Coding regions |
| Junk DNA | DNA that does not code for anything |
| messenger RNA (mRNA) | Middle man molecule |
| Mutation | Alteration to the sequence of bases |
| Nucleic acid | Macrommolecule. |
| Nucleotide | Make up DNA.. Have 3 parts.. Sugar, a phosphate group, and a base. |
| Phenotype | the physical manifestation of the instructions |
| Phylogenetic tree | a way of grouping organisms in hierarchical system that reflects the evolutionary history and relatedness of all organisms |
| Plasmid | Circular Pieces of DNA that can be incorporated into a bacterium’s genome |
| Point mutation | mutations where one nucleotide base pair in the DNA is replaed with another or a pair is insert/deleted |
| Polymerase chain reaction (PCR) | technique that allows a small piece of DNA to be duplicated repeatedly |
| Promoter site | a part of the Dna molecule that indicates the start of a gene. |

| Ribosomal subunits | the protein production factories where amino acids are linked together to produce the protein |
| Spontaneous mutations | Mutations that arise by accident as long strands of DNA and duplicate themselves. |
| Stem cell | cells that have the ability to become any cell by their surroundings |
| Tay Sachs disease | an individual inherits genes with a mutation that causes an inability to produce a critical lipid digesting enzyme in their lysosomes. Because of this, Lipids accumulate causing cells to choke. |
| Thymine | Pairs with Adenine |
| Trait | Any single characteristic or feature of an organism is referred to as this |
| Transcription | the process by which a gene’s base sequence is copied to mRNA |
| Transfer RNA (tRNA) | molecules that interpret the mRNA code and link specific base sequences with amino acids |
| Translation | the process where mRNA directs the production of a protein |
| Uracil | Pairs with Adenine |
| VNTRs (variable number of tandem repeats) | most highly variable parts of DNA |
| Wilmut, Ian | Scientist that reported they had cloned a sheep |
