Cell cycle was divided into four stages i.e. G${}_1$, S, G${}_2$, M by

• A. W. Flemming
• B. Strass burger
• C. Howard and Pelc
• D. Farmer

Answer 1

The correct option is C Howard and Pelc

Howard and Pelc divided cell cycle in four stage. The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells. Non-dividing cells not considered to be in the cell cycle. The stages are G${}_1$-S-G${}_2$-M. The G${}_1$ stage stands for "GAP 1". The S stage stands for "Synthesis". This is the stage when DNA replication occurs. The G${}_2$ stage stands for "GAP 2". The M stage stands for "mitosis", and is when and cytoplasmic division occur.
