During the meiotic division, the 

How many cells  are required for obtaining 16 haploid cells ?

There are 42 chromosomes in a cell. After a particular phase of mitosis, the number of chromosomes remain same. Name the phase.
I. Anaphase
II. Metaphase
III. Prophase
IV. Telophase

The presence of checkpoint during mitosis ensures the attachment of all chromosomal kinetochore proteins to the spindle fibres. The absence of attachment of kinetochore proteins produces a signal preventing mitosis to proceed to next stage. The occurrence of this check point is responsible for transition from

Skeletal muscle performs many functions in the body, including locomotion, support, and heat generation. Unlike most cells in the human body, skeletal muscle cells are multinucleate (having more than one nucleus per cell).
Which statement describes a circumstance that would produce a mature cell that has more than one nucleus?
