Thermosensitive plasmid
Most temperature-sensitive mutations affect proteins, and cause loss of protein function at the non-permissive temperature. The permissive temperature is one at which the protein typically can fold properly, or remain properly folded. At higher temperatures, the protein is unstable and ceases to function properly. These mutations are usually recessive in diploid organisms. Temperature sensitive mutants arrange a reversible mechanism and are able to reduce particular gene produc… WebbAt temperatures between 15 and 30 degrees C, the thermotolerant H plasmid transferred at about the same frequency as the temperature-sensitive plasmid. Elimination of some …
