Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the original cell.

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes (sperm or eggs).

Front

What are the stages of Mitosis?

Back

The stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the chromosomes condense and become visible, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes line up in the middle of the cell, and spindle fibers attach to the centromeres.

Front

What happens during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What are the four nitrogen bases of DNA?

Back

The four nitrogen bases of DNA are adenine, thymine, cytosine, and guanine.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands of nucleotides twisted around each other.

Front

What is sexual reproduction?

Back

Sexual reproduction is the process where two parents contribute genetic material to produce offspring.
