Unit 5 Vocab
RNA/DNA
| Term | Definition |
|---|---|
| Protein Synthesis | Formation of mRNA from DNA(transcription)and the conversion by tRNA to protein(translation). |
| DNA | Deoxyribonucleic Acid; Double stranded molecule that stays inside of the nucleus at all times and is used to create proteins. |
| RNA | Ribonucleic Acid; Single stranded molecule that transmits information from DNA to make proteins. |
| Nucleotide | Basic unit of DNA and RNA; consists of a 5-carbon sugar, nitrogen bases, and a phosphate group. |
| DNA Nucleotide | Deoxyribose Sugar, Bases GCAT, and Phosphate Group. |
| RNA Nucleotide | Ribose Sugar, Bases GCAU, and Phosphate Group. |
| DNA Nitrogen Bases | Guanine(G), Cytosine(C), Adenine(A), Thymine(T). |
| RNA Nitrogen Bases | Guanine(G), Cytosine(C), Adenine(A), Uracil(U). |
| Hydrogen Bond | Holds nitrogen bases together in DNA. |
| Covalent Bond | Holds sugars and phosphates and sugars and bases together. |
| DNA Replication | Process of copying DNA; occurs during interphase in mitosis and meiosis. |
| mRNA | Messenger RNA; carries message for making proteins from the Nucleus to the Ribosome. |
| tRNA | Transfer RNA; brings amino acids to the ribosome for assembly into a protein. |
| Transcription | Creation of mRNA from DNA strand. (INSIDE NUCLEUS). |
| Translation | Conversion of mRNA into protein using tRNA. (OCCURS IN RIBOSOMES) |
| Codon | Set of three nucleotides that code for specific amino acid. |
| Gene Regulation | Process where proteins are differentiated by the specific sequence of amino acids. |
| Hybridization | Combining different varieties of organisms; Hybrid (Mixture). |
| Mutation | Changes in genetic material. |
| Restrictive Enzymes | Used to cut DNA |
| Vectors | Methods for transferring foreign DNA into a host cell. Plasmids (Bacterical Cells) are a common type of vector. |
| Transgenic Organisms | Genetically modified organisms. Created by inserting forgein DNA into organisms. |
| Gel Electrophoresis | Also known as DNA fingerprinting; allows scientists to identity someone's DNA. |
| Stem Cells | Cells that are have no specialized function, which can be developed into a whole variety of cells by activating specific genes on the cells DNA. |
| Gene Therapy | Process through which specific gene sequences are inserted into an individual's cells to replace a defective or mutant allele. |
| Human Genome Project | Project that help identify the approximately 20,000 to 25,000 genes in human DNA. |
