Microbiology
| Question | Answer |
|---|---|
| Anticodon | binding site for being the correct codon |
| Cistrons | individual genes in an operon |
| Coupling | simultaneous synthesis of RNA and protein |
| Metabolic pathway | series of enzymes needed to complete a task and produce an end product such as an amino acid |
| Operon | gene cluster that is cotranscribed |
| Pathway | set of genes used for a complete task |
| Polysomes | structures with multiple ribosomes held together by the mRNA thread |
| Ribosomal RNA | (rRNA) RNA molecules are used in enzymatic processes--ribosomes are riboproteins--contain both rRNA and roteins in very large complexes |
| RNA polymerase | enzyme responsible for transcription--DNA-dependent RNA polymerase, DDRP |
| Transcription | step in molecular biology that follows DNA replication |
| Transfer RNA | (tRNA) important in protein synthesis--bring needed amino acids to appropriate site for addition during protein elongation |
| Translation | (protein synthesis) ribosomes--enzymes that perform translation--process by which mRNA is translated from language of nucleotides into language of amino acids |
| Triplet | each codon consists of three ribonucleotides in a row |
