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.
The given statement is False, it should read, "A theory and a law are already both supported by evidence and are equal, but they have different functions."
In the scientific method, a "Theory" and a "Law" are already both supported by evidence, but they serve different purposes.
The role of "Theory" in the scientific method is to provide a justification for the data collected through observations and results. As more data is gathered, it may be altered, enhanced, or even dismissed. While a "law" typically refers to an observed natural event that is true no matter how it is tested. It doesn't explain why the incident or event actually happened.
