Webb21 apr. 1995 · This strain carries a revertible mutant lac allele on an F plasmid and accumulates Lac + (lactose utilizing) revertants, but not unselected mutants, when placed on selective medium. These adaptive mutations are a subset of spontaneous types and their formation depends on the RecABC functions. WebbThe TA had the class create two recombinant clones in the multicopyplasmidvector pBR322. The first plasmid carried the wild-type lacpromoter-operator region and mutantZ-and Y-structural genes. The second plasmid carried the wild-type promoter-operator region and the Z+and Y+genes.

Plasmids are important agents for spread of genes between bacteria. Although they can transfer by general processes such as transformation (after release of DNA by lysis of its host) or transduction (by the packaging of plasmid DNA into phage particles), many plasmids (termed self-transmissible) are capable of transferring …

Webb10 aug. 2024 · The technique involves inserting a small portion of DNA, called a plasmid, into the yeast cells. The plasmid carries two genes: the first is essential for growth, and the other codes for one of the enzymes studied. The cell increasingly needs to make new plasmids in order to grow, but this also creates more enzymes. irecokWebb4 (a) An investigation was carried out to measure the rate of photosynthesis at different concentrations of carbon dioxide.
