Which of the following is the largest organelle in the cell?
The nucleus consists of genetic material in the form of a dense mass. It is surrounded by double membrane called nuclear envelope. It is the controlling centre of the cell.
Which of the following are the dense threadlike and rod like structures present in the nucleus?
Nucleus contains thread-like structures called chromosomes which are visible in a cell in the resting stage as chromatin threads. These threads unwind, shorten and thicken during cell division to become chromosomes
