Plasmid dna

After heat shock, immediately return the tubes to ice. For example, the plasmid pKC7 is a pBR derivative that carries the un-altered pMB1 replicon and under normal conditions, is maintained at 15 to 20 copies per cell. Both tubes should now be on ice. The second piece would contain the rest of the plasmid, from position all the way around to position for a total length of bp. Do not pick up any agar as it may inhibit the transformation process. Usually cells are lysed either using heat, or using alkaline conditions. Turn the plate a quarter turn and go back and forth several more times. Close the tube lid and put the tube on ice.

Close the tube lid and put the tube on ice. Count how many colonies are present on each plate. For example, bacterial antibiotic resistance genes are often carried on plasmids. The factors involved in this cost and its potential compensation remain largely unknown.

plasmid vector

Plasmids and chromosomes are replicated using the same enzymes, but plasmids are replicated and inherited independently from the bacterial chromosomes.
