Karyotyping Process: An Insight into Chromosome Analysis

The video tutorial explains the process of creating a karyotype, which is an image of an individual's chromosomes arranged systematically. It covers the steps involved, starting from collecting a blood sample, separating and growing white blood cells, blocking cell division using colchicine, releasing chromosomes, staining them with gaiemsa dye, and finally arranging them for analysis. The tutorial highlights the importance of each step in ensuring accurate chromosome analysis.

What is a karyotype?

• A laboratory tool for measuring blood pressure

• A type of genetic disorder

• An individual's set of chromosomes

• A type of cell

Which type of cells are used for karyotyping?

• Red blood cells

• Platelets

• White blood cells

• Plasma cells

Why are white blood cells chosen for karyotyping?

• They do not divide

• They are the most abundant cells

• They contain a nucleus with chromosomes

• They are the largest cells

What is the purpose of growing cells in a special medium?

• To increase their size

• To change their color

• To make them non-divisible

• To have enough cells to analyze

What role does colchicine play in karyotyping?

• It releases chromosomes from cells

• It grows the cells

• It blocks cell division in metaphase

• It stains the chromosomes

How are chromosomes released from white blood cells?

• By heating the cells

• By using a salt solution

• By freezing the cells

• By applying pressure

What is the purpose of staining chromosomes with Giemsa dye?

• To dissolve them

• To make them invisible

• To differentiate one chromosome from another

• To make them larger

What is the final step in the karyotyping process?

• Collecting a blood sample

• Growing cells

• Blocking cell division

• Cutting and arranging chromosomes
