Question & Answer

Q.1: What is the average cell cycle span for a mammalian cell?

Ans : The average cell cycle span for a mammalian cell is approximately 24 hours.

Q.2: Describe the events taking place during interphase.

Ans : Interphase involves a series of changes that a cell tor division. It is the period which the ceu experiences growth and DNA replication in an orderly manner. Interphase is divided into three phases. (i) GI phase (ii) S phase (iii) 62 phase GI phase — It is the stage during which the cell and prepares its DNA for replication. In this phase, the cell is metabolically active. S phase — It is the stage during which DNA synthesis occurs. In this phase, me amount of DNA (per cell) bubbles, but the chromosome number remains the same. 62 phase — In this phase, the cell continues to grow and prepares itself for division. The proteins and RNA required for mitosis are synthesised during this stage.

Q.3: What is \(\mathrm{G}_{\mathrm{o}}\) (quiescent phase) ot cell cycle?

Ans : \(\mathrm{G}_{\mathrm{o}}\) or quiescent phase is me stage wherein cells remain metabolically active, but do not proliferate unless called to do so. Such cells are used for replacing the cells lost during injury.

Q.4: Why is mitosis called equational division?

Ans : Mitosis is the process of cen divisbn wherein the chronusornes replicate and get ecpan distributed into two daughter ceus. The chromosome number in each cell is equal to that in the parent cell. i.e.. diploid. Hence. mitosis is known as equational division.

Q.5: Name the stage of cell cycle at which one of the following events occur: 
(i) Chromosomes are moved to spindle equator 
(ii) Centromere splits and chromatids separate 
(iii) pairing between homologous chromosomes takes place 
(iv) Crossing over between homologous chromosomes takes place

Ans : (i) Metaphase 
(ii) Anaphase 
(iii) Zygotene of meiosis I 
(iv) pachytene of meiosis I
