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:

Explanation:

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.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
