What is Mitosis?

Back

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

Front

What is the main difference between Mitosis and Meiosis?

Back

Mitosis produces two identical daughter cells, while Meiosis produces four genetically diverse daughter cells.

Front

What are Embryonic Stem Cells?

Back

Embryonic stem cells are pluripotent cells that can differentiate into any cell type in the body.

Front

What are Adult Stem Cells?

Back

Adult stem cells are multipotent cells that can differentiate into a limited range of cell types.

How do skin tones adapt to UV radiation?

Back

Darker skin tones provide protection against UV radiation, while lighter skin tones allow for better Vitamin D synthesis in low UV environments.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, resulting in two DNA molecules, each with one new strand and one original strand.

Front

What is the role of Vitamin D in the body?

Back

Vitamin D is essential for calcium absorption and bone health.

Front

What is Pluripotency?

Back

Pluripotency is the ability of a stem cell to differentiate into any cell type in the body.

Front

What is the significance of Folate in skin adaptation?

Back

Folate is important for DNA synthesis and repair, and its protection is crucial in environments with high UV radiation.
