DNA / RNA
| Term | Definition |
|---|---|
| DNA | deoxyribonucleic acid |
| RNA | ribonucleic acid |
| Transcription | DNA is copied to RNA |
| Translation | RNA creates amino acids |
| DNA Ligase | enzyme that connects two strands of DNA |
| Helicase | unzips DNA |
| Polymerase | enzyme that assembles DNA and/or RNA |
| Amino acids | monomer of proteins |
| Hydrogen bond | holds together 2 complementary strands of DNA |
| Codon | 3 nucleotide bases |
| Nucleotides bases of DNA | adenine (A), cytosine (C) , guanine (G), and thymine (T) |
| Nucleotide bases of RNA | adenine (A), cytosine (C), guanine (G), and uracil (U) |
| Pyrimidine bases | U, T, C |
| Purine bases | A, G |
| Stop codon | ends protein synthesis |
| Peptide bond | bond between amino acids in a protein |
| mRNA | messenger RNA -transfer code from DNA in the nucleus and carries to ribosomes in the cytoplasm |
| Anticodon | 3 nucleotides of tRNA that pair with codons on mRNA |
| Central dogma of molecular biology | information is transferred from DNA to RNA to proteins |
| Base Pair | 2 nitrogenous bases that connect to make the “rung” of the DNA ladder. |
