Answer:
Right handed,right handed,positive,left handed, negative,negative
Explanation:
In a circular bacterial chromosome the structure of DNA is a right handed double helix.
if DNA is twisted in the right handed direction,it becomes overwound. overwinding results in positive supercoiling.
If the DNA is twisted in the left handed direction it becomes underwound. Underwinding result negative supercoiling.
one effect of negative supercoiling in bacterial chromosome is to promote separation of the two strands of DNA in the double helix.
