Question

20. Which of the following statements about binary fission is false?
a. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter
cells, which are genetically identical to the parent cell.
b. Karyokinesis is unnecessary in prokaryotes because there is no nucleus.
c. Replication of the prokaryotic chromosome begins at the origin of replication and continues in
both directions at once.
d. The mitotic spindle draws the duplicated chromosomes to the opposite ends of the cell followed
by formation of a septum and two daughter cells.

Answer 2

The statement about binary fission 'the mitotic spindle draws the duplicated chromosomes to the opposite ends of the cell followed by the formation of a septum and two daughter cells' is FALSE.

Binary fission refers to an asexual mode of reproduction by which an organism separates a part of its body (usually a cell) to create two new bodies.

Binary fission represents the most common mode of asexual reproduction and occurs primarily in prokaryotes.

In binary fission, a parent cell divides to produce two genetically identical daughter cells.

During binary fission, there is no mitotic spindle formation within a cell nucleus.

In conclusion, the statement about binary fission 'the mitotic spindle draws the duplicated chromosomes to the opposite ends of the cell followed by the formation of a septum and two daughter cells' is FALSE.
