    What are the ends of the chromosome called?

    • Telomeres

    • Centromeres

    • Satellites

    • None of the above

    Correct Answer
    A. Telomeres
    Explanation
    Telomeres are the ends of the chromosome. They consist of repetitive DNA sequences that protect the chromosome from degradation and prevent the loss of important genetic information during DNA replication. Telomeres also play a crucial role in cell division and senescence. Centromeres, on the other hand, are regions in the chromosome that are responsible for the attachment of spindle fibers during cell division. Satellites refer to specific regions of the chromosome that have a different composition or structure compared to the rest of the chromosome. Therefore, the correct answer is Telomeres.

    Choose a primary reason that defines why chromosomes are condensed.

    • To provide cell division in daughter cells

    • For facilitating accommodation

    • Always condensed

    • For facilitating cell division

    Correct Answer
    A. To provide cell division in daughter cells
    Explanation
    Chromosomes are condensed to provide cell division in daughter cells. During cell division, the condensed chromosomes ensure that each daughter cell receives the correct number and type of chromosomes. Condensation allows the chromosomes to become more compact and organized, making it easier for them to be distributed evenly between the daughter cells. This ensures the accurate transmission of genetic information and helps maintain the integrity of the cell's DNA.

    What is a chromosome with a centromere near the middle called?

    • Acrocentric

    • Telocentric

    • Submetacentric

    • None of the above

    Correct Answer
    A. Submetacentric
    Explanation
    A chromosome with a centromere near the middle is called submetacentric. This means that the two arms of the chromosome are unequal in length, with one arm being longer than the other. The centromere is not exactly in the middle, but closer to one end. This type of chromosome is commonly found in many organisms, including humans.

    Earlier, centromeric DNAs were identified in

    • Bacteria

    • Yeast

    • Humans

    • Fungi

    Correct Answer
    A. Yeast
    Explanation
    Centromeric DNAs were previously identified in yeast. This suggests that yeast, along with other organisms such as bacteria, humans, and fungi, have centromeric DNAs. However, the question specifically asks for the earlier identification, implying that yeast was one of the first organisms in which centromeric DNAs were discovered.

    Who coined the term chromosome?

    • Boveri

    • Waldeyer

    • Hoffmeister

    • None of the above

    Correct Answer
    A. Waldeyer
    Explanation
    Waldeyer is credited with coining the term "chromosome" in 1888. He used the term to describe the thread-like structures that are visible in the nucleus of cells during cell division. This discovery was significant in advancing the understanding of genetics and the role of chromosomes in heredity. Boveri and Hoffmeister were also notable scientists in the field of cytology, but they did not coin the term "chromosome".

    How many satellite sequence elements are there in yeast centromere?

    • 1

    • 2

    • 3

    • 4

    Correct Answer
    A. 3
    Explanation
    Yeast centromeres typically consist of three satellite sequence elements. These elements play a crucial role in ensuring proper chromosome segregation during cell division. Each element contains a specific DNA sequence that binds to proteins involved in centromere function. The presence of three elements allows for the formation of a stable and functional centromere, ensuring accurate chromosome segregation and maintenance of genomic stability.

    Centromeric proteins are the ones that connect to the Spindle Fibers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    This statement is false. Centromeric proteins are not the ones that connect to the spindle fibers. Instead, centromeric proteins are responsible for holding sister chromatids together and ensuring their proper alignment during cell division. The spindle fibers, on the other hand, attach to the centromeres and help separate the sister chromatids during mitosis or meiosis. Therefore, the correct answer is false.

    Which of the following options is critically responsible for the even distribution of parental DNA?

    • Telomere

    • Spindle fiber

    • Centromere

    • Centrioles

    Correct Answer
    A. Centrioles
    Explanation
    Centrioles are critically responsible for the even distribution of parental DNA during cell division. They play a key role in forming the spindle fibers, which are responsible for separating the duplicated chromosomes. The spindle fibers attach to the centromere of each chromosome and pull them apart, ensuring that each new cell receives an equal and complete set of DNA. Without centrioles, the chromosomes would not be properly aligned and distributed, leading to genetic abnormalities in the resulting cells. Therefore, centrioles are essential for maintaining the genetic integrity and even distribution of parental DNA.

    Rate this question:

  • 10. 

    Which is the most suitable option for centromere?

    • Restricted chromosomal region

    • Connecting sister chromatids

    • Connecting to a spindle fiber

    • Facilitates even distribution

    Correct Answer
    A. Facilitates even distribution
    Explanation
    The centromere is the region of a chromosome that plays a crucial role in ensuring the even distribution of genetic material during cell division. It facilitates the attachment of spindle fibers, which are responsible for pulling apart sister chromatids and ensuring that each daughter cell receives an equal amount of genetic material. Therefore, the option "Facilitates even distribution" is the most suitable description for the centromere.
