When DNA duplicates what does that mean?
DNA is in the nucleus of a cell. When a cell divides (mitosis) the DNA in the nucleus must first duplicate. Basically an identical copy of the cells DNA is made. This creates another nucleus in the cell with a copy of the DNA. The cell it's self then divides, separating the 2 nuclei. Each cell having one each.
How many nucleoli are in each nucleus?
There is only one nucleoli in the nucleus of a cell. The nucleus of a cell is found in the cell's membrane.
What life function does the nucleus carry out?
The nucleus controls and tells each part of the cell what to do.
Which tissue has single nucleus in each cell?
cardiac cell
Where can you find cells that each have a cell wall a nucleus and chloroplasts?
In plantsExplanation...A plant cell contains a cell wall, a nucleus, and chloroplasts.-----------------------------------------------------------------------
What is a cell if it contains a nucleus?
A Eukaryotic Cell MUST contain a nucleus. A Prokaryotic Cell MUST NOT have a nucleus. A non-cell would be a virus.

What is the material outside the nucleus?
Cytoplasm surrounds the nucleus in each cell.
Which tissue has single nucleus in each cell?
cardiac cell
Was is and does a nucleus do?
The Nucleus of a cell basically tells every organelle what do,and how to do it. Also the nucleus tells each organelle what the whole cell needs and how to do it.
