Questions and Answers

What is the primary purpose of mitosis?

  • To create diverse genetic material
  • To merge two parent cells
  • To reduce the number of chromosomes
  • To form identical daughter cells (correct)

During which phase of mitosis do chromosomes align at the cell's equatorial plane?

  • Telophase
  • Metaphase (correct)
  • Anaphase
  • Prophase

Which of the following describes meiosis?

  • A type of cell division that occurs only in somatic cells
  • A process that results in two daughter cells with identical genetic material
  • A process resulting in daughter nuclei with half the amount of chromosomes (correct)
  • A process resulting in daughter nuclei with the same number of chromosomes

Cell division

The process of creating new cells from an existing cell.

Chromosome

A rod-shaped structure containing DNA, which is the genetic material.

Mitosis

Cell division that creates two identical daughter cells with the same number of chromosomes as the parent cell.

Meiosis

Cell Division that results in daughter cells with half the number of chromosomes as the parent cell.

Homologous chromosomes

These chromosomes share the same genes, but different versions of those genes. They pair up during meiosis to exchange genetic information.

What happens in Meiosis 1?

The first division in meiosis where homologous chromosomes separate. Each daughter cell receives one chromosome from each pair, leading to a reduction in chromosome number.

What happens in Meiosis 2?

Sister chromatids separate, resulting in four daughter cells with half the number of chromosomes as the original cell. This ensures genetic diversity.

Study Notes

Cell Division Definitions

  • Cell division is the process where new cells (daughter cells) form from a parent cell.
  • A chromosome is a rod-like structure containing DNA.
  • Mitosis is a cell division process creating daughter nuclei with the same chromosome number as the parent.
  • Meiosis is a cell division process resulting in daughter nuclei with half the chromosome number of the original nucleus.

Interphase and Mitosis Phases

  • Interphase is a stage prior to mitosis. Occurs before any other stages of mitosis.
  • Mitosis has four phases:
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
  • The result of mitosis is identical cells with the same genetic material as the parent cell.
