Answer:
The enzyme Topoisomerase functions to prevent super-coiling of the DNA molecule during replication.
Explanation:
- During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.
- A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.
- All topoiomereases are classified as Topoisomerase I and Topoisomerase II depending on whether they cleave one or two strands respectively.
- Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.
- Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.
B is correct.
<u>The cytoskeleton is responsible for cell shape. Scaffolding in general means a structure providing support. They build scaffolding to provide structural support during cell division and compartmentalize parts of the cell.</u>
The answer is D. measurement of energy found in food
negative impact for social is that some people tend to be self-consious when out in the public. for physicsl and emotional it is alright but they need to be carfeul when going outdie and ake sure they are hanging out with the right people
This condition is caused by a genetic defect found in the X chromosome, and therefore, you can conclude your answer from this info.
