Cyclins are a group of proteins which promote different phases of the cell cycle.

Large hydrophilic molecules can readily move unaided into and out of cells.

The process of cell death in which cell membranes remain intact but become bubbled and the nuclei condense is known as

Growth of a tissue due to hypertrophy occurs when cells increase in number.

Microtubules and microfilaments are the primary components of the

The proteins found in chromatin are called histones,are positively charged,and form spools.

The cell is the basic structural and functional unit in the body.
