Explanation / Answer

Mitois is a cell division that result in the formation of two daughter cells that have same number of chromosome as parent.

Four phase of eukaryotic cell cycle include G1, S , G2 and M

Mitosis is a cell division that resulted in two daughter cell formation where they have same number of chromosome whereas in cytokinesis two daughter cells have same amount of cytoplasm after division.

Cyclin and cyclin dependent kinase are two ways by which cell cycle is controlled.

Uncontrolled growth of cells resulted in the formation of tumor

Tumor is uncontrolled growth of cells. When the tumor spread from one part of the body to another it is called cancer.

Ras protein is responsible for signal transmission in the cell

The material through which chromosome are composed like genetic material DNA or RNA is called chromatin. Homologous are pair of chromosome that are similar in shape, size and locus.

Chromosomes are made up of DNA and RNA

Cell cycle consist of interphase, prophase , metaphase, anaphase and telophase

Interphase, mitotic phase and cytokinesis are the phase of cell cycle

Somatic cells are body cell different from gametes
