In a cell without a nucleus (prokaryotic cell), DNA is usually found in a circular shape called a nucleoid, located in the cytoplasm. The DNA is not associated with histone proteins as in eukaryotic cells.
A cell consists of three main parts---the nucleus, the cell "stuff" called cytoplasm, and the outer cell membrane.
Transcription takes place in the nucleus of a cell.
nucleus
Plant cells must have a nucleus to make cells.
The nucleus. because the nucleus controls the whole cell, it cannot divide without it telling it to. =]
Nucleus is called as the boss of a cell , it controls all the works that take place in the cell.
Transcription takes place in the nucleus of the cell.
The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. In prokaryotes which lack a cell nucleus, the cell cycle occurs via a process termed binary fission.
The cell's control center is the nucleus. It contains DNA, which provides the instructions for the activities that take place inside the cell. The nucleus regulates the cell's functions by controlling gene expression and directing cellular processes.
