Genetics
| Term | Definition |
|---|---|
| Nucleotide | basic unit or building block of DNA & RNA; composed of a sugar, a phosphate, and a nucleic acid |
| Adenine | nucleic acid found in both DNA & RNA; pairs with Thymine in DNA; pairs with Uracil in RNA |
| Guanine | nucleic acid found in both DNA & RNA; pairs with Cytosine |
| Cytosine | nucleic acid found in both DNA & RNA; pairs with Guanine |
| Thymine | nucleic acid only found in DNA; pairs with Adenine |
| Uracil | nucleic acid only found in RNA; pairs with Adenine |
| DNA Backbone | form the sides of the DNA/RNA molecule; made of sugar and phosphate |
| Ribosome | found in the cytoplasm of living cells and serves as the site of protein synthesis |
| Codon | three consecutive nucleotides that specify a single amino acid |
| Translation | process that decodes mRNA to make proteins |
| Amino Acid | join together to make proteins |
| Anticodon | three adjacent nucleotides in transfer RNA that binds to a corresponding codon in messenger RNA and designates a specific amino acid during protein synthesis. |
| Transcription | process by which messenger RNA is synthesized from a DNA template |
| Gene | part of DNA sequence that codes for a specific trait |
| tRNA | type of nucleic acid that transports a specific amino acid to a ribosome during protein synthesis |
| Chromosome | single molecule of DNA bonded to various proteins and that carries the genes determining heredity |
| mRNA | type of nucleic acid that carries genetic information from the cell nucleus to ribosomes in the cytoplasm; serves as a template for protein synthesis; synthesized from a DNA template during the process of transcription |
| rRNA | type of nucleic acid that is the permanent structure of a ribosome |
| Trait | characteristic defined by the expression of a protein |
