amplification,gene 《英文msh词典》Amplification,Gene ; [入口词] Amplification,Gene ; [主题词] Gene Amplification ; [英文释义] A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid,or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over,uptake of DNA from lysed cells,or generation of extrachromosomal sequences from rolling circle replication.
amplification techniques,rna 《英文msh词典》Amplification Techniques,RNA ; [入口词] Amplification Techniques,RNA ; [主题词] Nucleic Acid Amplification Techniques ; [英文释义] Laboratory techniques that involve the in-vitro synthesis of many copies of DNA or RNA from one orginal template.
amplification techniques,nucleic acid 《英文msh词典》Amplification Techniques,Nucleic Acid ; [入口词] Amplification Techniques,Nucleic Acid ; [主题词] Nucleic Acid Amplification Techniques ; [英文释义] Laboratory techniques that involve the in-vitro synthesis of many copies of DNA or RNA from one orginal template.
