| RNA | Ribonucleic Acid |
| mRNA | carries the instructions for protein synthesis from the DNA to the ribosome where it acts as a blueprint |
| tRNA | delivers amino acids to the mRNA blueprint at the ribosomes |
| Genetic Engineering | manipulating the genes of organisms |
| Transcription | process in which part of the nucleotide sequence of DNA is copied into a complimentary sequence of DNA |
| Translation | decoding of mRNA message into an amino acid |
| Uracil | nitrogen base that replaced thymine in RNA; matches up with adenine |
| Recombinant DNA | new DNA that is created from two different DNA molecules |
| Plasmid | small piece of circular DNA in bacteria (often used in genetic engineering) |
| Restriction Enzyme | enzyme able to cut DNA |
