    Where is DNA located in a eukaryotic organism?

    • The plasma membrane

    • The nucleus

    • The fragments of deterorated nucleus walls

    Correct Answer
    A. The nucleus
    Explanation
    In eukaryotic organisms, DNA is located in the nucleus. The nucleus is a membrane-bound organelle that houses the genetic material of the cell, including the DNA. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The plasma membrane, on the other hand, surrounds the cell and separates it from its external environment. The fragments of deteriorated nucleus walls mentioned in the options are not a valid location for DNA in eukaryotic organisms.

    How are chromosomes paired up on a karyotype?

    • By the size and band combination

    • By the number of centromeres it has

    • By the wieght of the chromosome

    Correct Answer
    A. By the size and band combination
    Explanation
    Chromosomes are paired up on a karyotype based on their size and band combination. This is because chromosomes can be distinguished and classified based on their size and the unique banding patterns they exhibit when stained. By analyzing these characteristics, chromosomes can be paired up and arranged in a karyotype, which is a visual representation of an individual's chromosomes. This allows for the identification of any abnormalities or genetic disorders.

    Rate this question:

  • 15. 

    Is a female or male more likely to get a sex linked disorder?

    • Male

    • Female

    Correct Answer
    A. Male
    Explanation
    Males are more likely to get a sex-linked disorder because these disorders are caused by genes located on the sex chromosomes (X and Y). Males have one X and one Y chromosome, while females have two X chromosomes. If a male inherits a faulty gene on his X chromosome, he does not have a second X chromosome to compensate for it. However, females have two X chromosomes, so even if one X chromosome has a faulty gene, the other X chromosome can often compensate for it. Therefore, males have a higher likelihood of developing sex-linked disorders.

    Why would it be more difficult to pair up chromosome on a karyotype if the chromosomes where unstrained?

    • The number of actual chromosomes would be difficult to see

    • It wouldnt

    • The size and the bands would be harder to see

    Correct Answer
    A. The size and the bands would be harder to see
    Explanation
    If the chromosomes were unstrained, it would be more difficult to pair them up on a karyotype because the size and bands on the chromosomes would be harder to see. The bands on the chromosomes help in identifying and matching them, and if they are not visible or clear, it would be challenging to accurately pair them up. Therefore, the size and bands being harder to see would make it more difficult to pair up the chromosomes on a karyotype.
