DNA replication occurs during which phase of the eukaryotic cell cycle?
wariber [46]

In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.

Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).

Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.

I really hope this helps!

A patient breaks a leg. predict which model a doctor will use to show where the break is
VMariaS [17]

A doctor can use a 2D image model to show where the break is.

When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.

The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.

Each of these devices uses 2D image technology to show the result of the scan.

So, a model that can be used by a doctor to determine the location of the break is 2D image.
