Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?
In order for genetic information to be transferred into daughter cells.
In order for the cell to be able to increase in size.
In order for the DNA to be contained in the nucleus.

Interphase has 3 stages; G1, S, and G2. What happens during S phase?
Cells grow and carry out normal functions
Cells copy organelles and prepare for a critical checkpoint
The cell splits into two new daughter cells
The cell makes a copy of its DNA
The protein that associates with centromere, in which spindle microtubules attach
(a)
These are the three types of microtubules; except
Astral microtubules
Kinetochore microtubules
Astro microtubules
Polar microtubules
The microtubules from opposite poles that do not attach to the kinetochores but do overlap at the midpoint between the two poles are referred to as
Kinetochore microtubules
Polar microtubules
Spindle microtubules
Astral microtubules
The microtubule originating from the centrosome which does not connect to a kinetochore but associated with proteins on plasma membrane is
Astral microtubules
Kinetochore microtubules
Spindle microtubules
Interpolar microtubules
Which of this states the chromosomal behaviour during Telophase?
Chromosomes are aligned along metaphase plate
Chromosomes are decondense and uncoil
Sister chromatids are pulled to the opposite poles
Chromatin fibres and condensed and thickened
Which of this states the chromosomal behaviour during Anaphase?
Chromosomes are aligned along metaphase plate
Chromatin fibres are condensed to chromosomes
Sister chromatids are pulled to the opposite poles
Chromatids are decondense to chromatin
Which of this states the chromosomal behaviour during Metaphase in mitosis?
Chromosomes are aligned along metaphase plate
Chromatin are aligned along the metaphase plate
Homologous chromosomes are aligned along the metaphase plate
Bivalent are aligned along the metaphase plate
These states the chromosomal behaviour in mitosis, except.
Centrosomes move to the opposite poles
Chromatin fibres are condensed to chromosomes
Sister chromatids are pulled to the opposite poles
Chromatids are decondense to chromatin
