Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix
Answer:
are you talking about for a person or an animal?
We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
