RossCharacterization of cell lines is important to ensure research reproducibility and reliability. It helps to confirm the identity, purity, and characteristics of the cells being used in experiments, which can impact experimental results and interpretations. Proper characterization also ensures that cells maintain consistent behavior across experiments, leading to more accurate conclusions.

What is mataphase?
Metaphase is the stage of mitosis where the chromosomes line up along the equatorial plane of the cell. This alignment is crucial for ensuring that each daughter cell will receive an equal and identical set of chromosomes during cell division.
Why is the vacuole important to the plant cell?
The vacuole in a plant cell plays a vital role in maintaining turgor pressure, storing nutrients, waste products, and pigments, and facilitating plant growth by controlling cell expansion. It also helps regulate the cell's internal environment, store toxic waste products, and provide structural support to the cell.
Why is colchisine used in karyotypic determination?
Colchicine is used in karyotypic determination to arrest cells in metaphase of mitosis, where chromosomes are condensed and distinct, making them easier to visualize and analyze under a microscope. By stopping the cell cycle at this stage, colchicine helps to obtain a snapshot of the complete set of chromosomes in a cell, known as karyotype, which is important for identifying chromosomal abnormalities and genetic disorders.
What does the white line in a horses hoof do?
The white line in a horse's hoof is the area that connects the insensitive outer hoof wall to the sensitive inner structures of the hoof. It provides strength and support to the hoof. Maintaining the white line is important for overall hoof health and to prevent issues such as abscesses.
What is the most important function for glycoproteins and glycolipids of animal cell membrane?
They help to stabilize the membrane structure as they form hydrogen bonds with water molecules in the fluid surrounding the cell. They also act as receptors and help in cell identification, hormonal responses and neuron-transmission. Glycoproteins can act as carrier proteins.
