A, I think, please let me know if this is right or wrong.
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.
The high concentration nutrients in sieve tubes causes water to move by osmosis from xylem into the phloem cells.
<h3>What is osmosis?</h3>
Osmosis is the movement of water across a semipermeable membrane as a result of solute concentration gradient.
The The high concentration nutrients in sieve tubes causes entry of water through osmosis. It leads to movement of water from xylem into the phloem cells by osmosis.
In conclusion, osmosis enables movement of water in plants.

Answer:
Hox genes regulate sex determination in mammals.
-Hox genes regulate flower development.
-Hox genes encode transcription factors that respond to steroids.
-Hox genes encode transcription factors with a DNA-binding domain called a homeo box and regulate development of the vertebrate body plan
- Hox genes are transcription factors that bind to specific DNA sequels called homeodomains
and regulate development of the vertebrate body plan.
Hox genes are transcription factors that bind to specific DNA sequences called
