Question

In mitosis, a cell having 2n chromosomes, would form daughter cells having how many chromosomes?

Answer 1

$\huge\underbrace\mathfrak\red{answer}$

If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.

Answer 2

In mitosis, a cell having 2n chromosomes would form daughter cells having 2n chromosomes.

• Cell divisions are of two kinds: Mitosis and Meiosis.
• Mitosis is the division of a cell into two identical daughter cells with the same number of chromosomes as in the parent cell.
• It occurs in somatic cells.
• It occurs in the following phases: Prophase, Metaphase, Anaphase, and Telophase.
• In Prophase, the chromatin fibres shorten and condense to form chromosomes. The nucleolus and nuclear membrane disappear. The centrosome divides into two centrioles and moves towards the opposite poles.
• In Metaphase, the chromosomes arrange themselves upon the equator of the spindle.
• During anaphase, the sister chromatids divide and separate.
• In telophase, the chromatic lengthens to form chromatin threads, nuclear membrane and nucleolus reappear.
