What is the function of topoisomerase in dna replication?

Biology
1 answer:
enot [183]3 years ago
5 0

Answer: Topoisomerases (or DNA topoisomerases) are enzymes that participate in the overwinding or underwinding of DNA. The winding problem of DNA arises due to the intertwined nature of its double-helical structure. During DNA replication and transcription, DNA becomes overwound ahead of a replication fork.

In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep
Ipatiy [6.2K]

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

<u>Eukaryotes </u>

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

<u>Bacteria </u>

1. Option-3 as DNA replication process separates the strand of the DNA.

<u>Both </u>

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.

Please help me, In your opinion ( I'll give Brainliest):
MrMuchimi

I think this depends on you  because it your choice for yourself but I'll just state some information or facts about this career.

  • The field is a specialization in biomedical engineering that can take four to eight years to master.
  • Genetic engineering has been applied in numerous fields including research, medicine, industrial biotechnology and agriculture. In research GMOs are used to study gene function and expression through loss of function, gain of function, tracking and expression experiments.
  • Success rates are incredibly low; on average, less than 10% of embryos survive to birth and a smaller percentage of those born survive to adulthood.
  • The field of genetics allows you to work in medical as well as scientific research.
  • To become a genetic engineering research scientist, you need a doctoral degree in a biological science.
  • Genetic engineers can earn anywhere from $44,320 to $139,440 a year.

Hope this helps and if you could mark me as brainliest. Thanks!
