Impact of Genomics
| Question | Answer |
|---|---|
| potential properties, genetic makeup | genotype |
| expressed properties | phenotype |
| sequencing and molecular characterization of genomes | genomics |
| enzyme synthsizes DNA, proofreads and repairs DNA | DNA polymerase |
| enzyme that joins sequences together, makes covalent bonds, joins Okazaki fragments | DNA ligase |
| synthesis of complementary strand of RNA from a DNA template | transcription |
| RNA enzyme that removes introns and splices exons together | ribosomes |
| copies RNA from a DNA template | RNA polymerase |
| non-coding regions | introns |
| coding regions | exons |
| protein synthesis, mRNA translated in codons | translation |
| AUG | start codon |
| UAA, UAG, UGA | stop codons |
| change in genetic material | mutation |
| affects single nitrogenous base - silent, missense, nonsense | base substitution |
| insertion or deletion of one or more nucleotide pairs | frameshift mutation |
| uses bacteria to identify mutagens, cannot synthesize histidine | Ames test |
| make multiple copies of DNA, polymerase chain reaction | PCR procedure |
| exchange of genes between 2 DNA molecules | genetic recombination |
| first genetic recombination to be discovered, naked DNA | transformation |
| cell to cell contact genetic recombination, can make large quantities | conjugation |
| uses bacteriophages | transduction |
| circular, self-replicating, small extra-chromosomal DNA molecules | plasmid |
| "jumping genes", small segments of DNA that can move from one region of DNA to another | transposons |
