Which enzyme is responsible for relieving the torsional stress caused by dna unwinding in the process of dna replication?

Allushta [10]

The process of DNA replication leads to the build up of torsional stress in the synthesised DNA helix. This torsional stress is due to the presence of tighter turns within the newly synthesised DNA helix. The DNA replication machinery then recruits the DNA topoisomerase enzyme to release the torsional stress by cleaving the synthesised DNA strands, followed by their ligation.

<h2>Fluorescence in situ hybridization (FISH)</h2>

Explanation:

Fluorescence in situ hybridization (FISH) is a macromolecule acknowledgment innovation dependent on the correlative idea of DNA or DNA/RNA twofold strands.

Chosen DNA strands joined with fluorophore-coupled nucleotides can be utilized as tests to hybridize onto the corresponding groupings in tried cells and tissues and afterward envisioned through a fluorescence magnifying instrument or an imaging framework. This innovation was at first evolved as a physical mapping apparatus to outline qualities inside chromosomes.
