DNA/RNA Re/Preview
Components of DNA, transcription, translation, genes
| Term | Definition |
|---|---|
| Adenine | one of the base pairs, pairs with Thymine |
| Thymine | one of the base pairs, pairs with Adenine |
| Guanine | one of the base pairs, pairs with Cytosine |
| Cytosine | one of the base pairs, pairs with Guanine |
| Uracil | one of the base pairs in RNA ONLY (replacesThymine), pairs with Adenine |
| Transcription | synthesis of an RNA molecule from a DNA template |
| Translation | when the sequence of bases of an mRNA strand is converted into the sequence of amino acids of a protein |
| Polymer | molecule composed of 2 or more monomers; makes up biomolecules |
| Monomer | small unit that makes up a polymer (mono + mono = poly) |
| Synthesis | to place/put together; to build or make |
| DNA | also known as Deoxyribonucleic Acid; the double-strand polymer made up of individual nucleotides |
| Nucleotide | the monomer that makes up DNA and RNA |
| RNA | also known as Ribonucleic Acid; the single-strand polymer made up of individual nucleotides |
| Gene | sequence of DNA that codes for a protein and thus determines a trait; factor that is passed from parent to offspring |
| Nitrogen Base | a.k.a. Nitrogenous Base or Nitrogen Base Pair or Base Pair. Can be Adenine, Thymine, Cytosine, or Guanine (or Uracil in RNA) |
| Cell | smallest unit of life. Can be prokaryotic or eukaryotic |
| Genetic Information | nucleic acids such as DNA or RNA, can be found in all organisms down to the smallest cell, as well as viruses |
| Nucleus | where genetic information such as DNA is found, in eukaryotic cells only |
| Ribosome | cell organelle found throughout the cytoplasm; site of protein synthesis |
| Protein | biomolecule that contains carbon, hydrogen, oxygen, and nitrogen (CHON), needed by the body for growth and repair |
| Gene Regulation | the process of controlling which genes in a cell's DNA are expressed (used to make a protein) |
