Solution
Question
Answer
Explanation
7) What is the sequence of events in a typical eukaryotic cell cycle
B)G1 to S to G2 to mitosis to cytokinesis
In most eukaryotic cells, the division cycle of is divided into four discrete phases: G1, S, G2 and
M, M phase is followed by cytokinesis.
8) In which stage below in Mitosis, centromeres/chromosomes are aligned at the equator phase
of the cell?
C) Metaphase
When the prometaphase ends and metaphase begins, the chromosomes will be seen aligned along
the cell equator.
9) Which one below is not the Cell cycle check point?
B)S—G2
G1/S checkpoints, G2/S checkpoint and M checkpoint, these are the three checkpoints found in
the cell cycle
10) The pairing of chromosomes along their lengths, which is essential for crossing over referred

2. to as
B)synapsis
During synapsis only you can see the pairing up of the homologous chromosomes side by side
during meiosis I. Here each homologue pairs along its entire length to facilitate crossing over.
11) Which of the following statements about crossing over is false?
B)Crossing over takes place between sister chromatids
The exchange of chromosome segments between non-sister chromatids is seen during crossing
over and this will occur during the production of gametes.
12) Chromosomes fail to separate during meiosis, leading to abnormal number of chromosomes
B)Non-disjunction
During cell division, failure of homologous chromosomes or sister chromatids to separate
properly is known as Nondisjunction. Monosomy (2n-1) or trisomy (2n+1) are the example for
this
