To transform bacteria with plasmids, technicians first make the bacteria competent (capable of taking up DNA) by placing them in calcium chloride and chilling them. Plasmid is then added to the competent bacteria and the plasmid/bacteria combination is taken through a few more steps to make the bacteria take up DNA. In your experiment, should you treat a tube of bacteria that you do not add plasmid to exactly as you do the tube of bacteria that you will transform:
The Plasmid is known as a genetic structures present in a cell that can be replicated independently of the chromosomes. Bacteria can take up from the foreign DNA in a process is known as the transformation.
This experiment helps to give control demonstrating that the arc (antibiotic-resistance colonies) which occurs on the plate is known as a result of the Plasmid which is taken up by the cells. If there is no Plasmid, then there should be no growth present on the antibiotic plates.
question: which statement best describes the different properties of metals?
answer: they are shiny and bend without breaking.
since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.
hope this , have a good day. c;
