Arrange the following events of meiosis I in the correct sequence:
(a) Crossing over
(b) Synapsis
(c) Terminalisation of chiasmata
(d) Disappearance of nucleolus
a, b, c, d
b, a, c, d
b, c, a, d
c, b, a, d
During meiosis, which of the following events occurs immediately after synapsis?
Crossing over
Terminalisation of chiasmata
Disappearance of nucleolus
Segregation of homologous chromosomes
In which stage of meiosis I does terminalization of chiasmata occur?
Diplotene
Pachytene
Zygotene
Leptotene
Which of the following events is NOT directly associated with the pairing of homologous chromosomes during meiosis?
Disappearance of nucleolus
Crossing over
Formation of chiasmata
Synapsis
During cell division, the cytoskeleton plays a vital role in:
DNA replication
RNA transcription
Chromosome segregation
Protein folding
Which statement about meiosis is NOT correct?
Meiosis results in four haploid daughter cells.
Meiosis produces genetically identical daughter cells.
Meiosis is essential for sexual reproduction in animals.
Meiosis involves two rounds of cell division.
During which phase of meiosis does the centromere split?
Anaphase I
Anaphase II
Metaphase I
Metaphase II
In meiosis, sister chromatids are held together at the centromere. Separation of sister chromatids and division of the centromere occurs during which stage?
Prophase II
Metaphase II
Anaphase II
Telophase II
Which of the following events does not occur during anaphase II of meiosis?
Sister chromatids separate
Centromeres divide
Homologous chromosomes separate
Chromosomes move to opposite poles
If a cell fails to divide its centromeres during meiosis II, what would be the immediate consequence?
Homologous chromosomes would not separate
Sister chromatids would not separate
DNA replication would not occur
The cell would enter interphase
