  • 2. 
    This is: - ProProfs

    This is:

    • A chromosome

    • A Karyotype

    • F.I.S.H

    Correct Answer
    A. A Karyotype
    Explanation
    A karyotype is a visual representation of an individual's chromosomes, arranged in pairs and organized by size and shape. It allows for the identification of any abnormalities or genetic disorders, as well as the determination of an individual's sex. This answer is correct because it accurately identifies the given image as a karyotype, which is a common diagnostic tool used in genetics and cytogenetics.

    This is an example of: - ProProfs

    This is an example of:

    • The structure of a cell

    • The mapping system

    • A Karyotype

    • An abnormal chromosome

    Correct Answer
    A. The mapping system
    Explanation
    The correct answer is "The mapping system." This is because the question is asking for an example, and the other options (the structure of a cell, a karyotype, and an abnormal chromosome) are not examples of anything. The mapping system, on the other hand, is a specific example that can be used to explain or illustrate a concept or process.

    Rate this question:

  • 4. 

    Down syndrome comes from:

    • A deletion in the 21st chromsome

    • A copy of the 21st chromosome

    • The 21st chromosome attaching to the 23rd chromosome

    • The deletion of the 20th chromosme

    • None of the Above.

    Correct Answer
    A. A copy of the 21st chromosome
    Explanation
    Down syndrome is caused by the presence of an extra copy of the 21st chromosome. This additional genetic material disrupts the normal development and causes the characteristic physical and cognitive features of Down syndrome.

    The most important technology used in cytogenetics is:

    • Microscopes

    • Centrifuges

    • F.I.S.H.

    • Karyotypes

    • Test Tubes

    Correct Answer
    A. F.I.S.H.
    Explanation
    F.I.S.H. stands for fluorescence in situ hybridization, which is a technique used in cytogenetics to detect and locate specific DNA sequences on chromosomes. It involves the use of fluorescent probes that bind to specific DNA sequences, allowing researchers to visualize and analyze the chromosomes under a microscope. F.I.S.H. is a crucial technology in cytogenetics as it helps in the diagnosis of genetic disorders, identification of chromosomal abnormalities, and understanding the organization and behavior of chromosomes.

    Cytogenetics has been around since:

    • The 18th Century

    • The 19th Century

    • The 20th Century

    • The 21 Century

    • None of the above

    Correct Answer
    A. The 20th Century
    Explanation
    Cytogenetics is the study of chromosomes and their abnormalities, which involves analyzing the structure, function, and behavior of these genetic materials. The field of cytogenetics began to develop in the early 20th century with the discovery of chromosomes and their role in heredity. Scientists such as Thomas Hunt Morgan and Theophilus Painter made significant contributions to cytogenetics during this time. Therefore, the correct answer is "The 20th Century."
