Question 3 :
Assertion: Interphase occupies $75-95\%$ of the total generation time.
Reason: Interphase (I-phase) is the long non-dividing phase.
Question 6 :
Cure for some cancers can be achieved in the ........... phase of the cell cycle.
Question 7 :
The synthesis of RNA and protein takes place in which phase of the cell cycle?
Question 8 :
State whether th following statements are true or false.<br>The so-called resting nucleus is not really resting.
Question 9 :
How many chromosomes will the cell have at $G_1$ after S and after M phase respectively, if it has 14 chromosomes at interphase?
Question 10 :
DNA and histone proteins are synthesized during which of the following phase of cell cycle?
Question 14 :
Chromatin fibers duplication, Genetic material- 4C, Histone Protein Synthesis, membranous organelle duplication, DNA replication, centriole duplication. How many of the above features are associated with the synthesis phase of the cell cycle?
Question 18 :
A cell that has 36 chromosomes, at the start of interphase will have ........... at the conclusion of meiosis.
Question 19 :
Choose the correct answers from the alternatives given :<br>A particular cell has half as much DNA as some of the other cells in a mitotically active tissue. The cell in question could be in
Question 20 :
The replication of DNA takes place during which phase<br/>(I) Mitosis<br/>(II) G$_1$phase<br/>(III) S phase<br/>
Question 21 :
A cell divided every one minute. At this rate division, it can fill a 100 ml of beaker in one hour. How much time does it take to fill a 50 ml beaker?
Question 22 :
If egg of an organism has $10pg$ of DNA in its nucleus. How much DNA would a diploid cell of same organism have in ${G}_{2}$ phase of meiosis?
Question 23 :
Assertion: Cell division is necessary because it is a physiological process bound to occur as a rule of nature.
Reason: Division of nucleus is followed by division of cytoplasm.
Question 24 :
Post mitotic gap phase and synthetic phases of cell cycle are also respectively referred to as:
Question 25 :
When cell division fails after S - phase (DNA replication) in a diploid cell, the ploidy is
