Cells - The Unit of Life
Which of the following statements is not correct regarding colchicine?
Match column I with column II and select the correct option from the given codes. Sr.no List I Sr.no List II A. Disintegration of nuclear membrane 1. Anaphase B. Appearance of nucleolus 2. Prophase C. Division of centomere 3. Telophase D. Replication of DNA 4. S- phase
Prophase is the short phase where there is no pairing of the chromosome and this is the first phase where the disintegration of the nuclear membrane takes place and the chromatin appears as a ball of wool.
During the S phase which is the synthetic phase of the interphase and here the DNA replication takes place and its amount become double.
In the anaphase, the division of centromere takes place and the chromatids separate and move towards opposite poles.
Telophase is the stage where the nuclear membrane starts integrating and all the cellular organelles can be seen again and here the nucleus starts forming.
Thus, the correct answer is 'A-(ii),B-(iii),C-(i),D-(iv).'

The following are stages in the cell division in plants 1. Anaphase 2. Prophase 3. Telophase 4. Metaphase What is their correct sequence?
