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
Water is one of the fundamental elements.
Water molecules bond with each other through hydrogen bonding. This type of bonding is a strong one as compared to other intermolecular forces present. The partial positive of the oxygen attracts the partial positive of the hydrogen so they bind to each other. In this way, they act as little magnets.
Bacteria transcription is a process by which bacteria DNA is transcribed to produce messenger RNA which is then translated to form proteins. Unlike in Eukaryotes,in bacteria the transcription and translation can occur simultaneously. A bacteria transcription complex contains 8 base pairs of RNA-DNA hybrid.
