Cell cycle and Cell Division

Fruit fly body cells have 8 chromosomes. After meiosis, you would expect the resulted gametes, each one has ______

• 16 chromosomes.

• 8 chromosomes.

• 4 chromosomes.

• 2 chromosomes.

In this phase cell has quantity of DNA in each cell is 4C

• G1

• S

• G2

• Metaphase

DNA replicates ______

• Only once in each cell cycle

• Once in mitotic cell cycle, once in meiotic I (Reductional division) and Once in meiotic II (equational division)

• Twice in each cell cycle

• Once in mitotic cell cycle and Once in meiotic II.

Significance of mitosis is in –

• 
  Producing identical cells genetically similar to mother cell

• 
  In reducing the chromosome (2N → N)

• Increasing cellular mass

• Producing 4 cells with genetic variations.

At metaphase of mitosis, each chromosome consists of _________ chromatid(s) _________ centromere(s).

• 4, 1

• 2, 1

• 2, 2

• 4,2

Which of the following terms means cytoplasmic division?

• Karyokinesis

• mitosis

• cytokinesis

• cell cycle

This stage is ______.

• Metaphase in Mitotic division

• Anaphase 1

• Metaphase 1

The reason of Genetic variation is ______.

• Satellite DNA

• Crossing over

• Chiasmata

• Mitotic division

The picture shows _____ .

• Metaphase I

• Metaphase II

• Anaphase I

• Anaphase II

A new nuclear membrane is formed around the chromosomes in _____.

• Prophase

• Metaphase

• Anaphase

• Telophase
