Question

Is a cell able to survive without nucleus?

Answer 1

Yes, but not any cell.

Explanation:

RBCs, for example, don't have a nucleus but they are completely functional. But this is not the case in any cell. Some cells do survive but the majority die when the nucleus is severely damaged.

Answer 2

Yes and no.

Explanation:

There are cells that live without nucleus (RBCs for example) and it's related to the function of the cell.

However, if you take a cell with nucleus and remove it, cell won't live.
