    What is the function of DNA ligase in recombinant technology?

    • Cut DNA into many fragments

    • Carry DNA into a new cell

    • Link together newly joined fragments of DNA

    • Make millions of copies of a specific segment of DNA

    • Separate fragments of DNA by their length and electrical charges

    Correct Answer
    A. Link together newly joined fragments of DNA
    Explanation
    DNA ligase is an enzyme that plays a crucial role in recombinant technology by linking together newly joined fragments of DNA. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides, sealing any gaps or nicks in the DNA backbone. This process is essential for the successful construction of recombinant DNA molecules, such as plasmids or vectors, where different DNA fragments need to be joined together. DNA ligase ensures the integrity and stability of the recombinant DNA molecule by sealing any breaks in the DNA backbone, allowing for the proper functioning of the inserted genes or DNA sequences.

    What is the function of the polymerase chain reaction in genetic engineering?

    • Cut DNA into many fragments

    • Carry DNA into a new cell

    • Link together newly joined fragments of DNA

    • Make millions of copies of a specific segment of DNA

    • Separate fragments of DNA by their length and electrical charges

    Correct Answer
    A. Make millions of copies of a specific segment of DNA
    Explanation
    The function of the polymerase chain reaction (PCR) in genetic engineering is to make millions of copies of a specific segment of DNA. PCR is a technique that allows scientists to amplify a small amount of DNA into a large quantity. This is done by using specific primers that bind to the DNA segment of interest, and then using a heat-stable DNA polymerase to synthesize new DNA strands. Through a series of temperature cycles, PCR can exponentially replicate the target DNA segment, making it easier to study, manipulate, and analyze.

    What is the function of a vector in genetic engineering?

    • Cut DNA into many fragments

    • Carry DNA into a new cell

    • Link together newly joined fragments of DN

    • Make millions of copies of a specific segment of DNA

    • Separate fragments of DNA by their length and electrical charges

    Correct Answer
    A. Carry DNA into a new cell
    Explanation
    A vector in genetic engineering is a DNA molecule that is used to carry foreign DNA into a host cell. It acts as a vehicle to transport the desired DNA segment into a new cell where it can be expressed or replicated. This allows genetic engineers to introduce specific genes or genetic material into cells for various purposes such as gene therapy, production of recombinant proteins, or studying gene function.

    Polymerase chain reactions can be used to recognize an infection before the body has started to make antibodies, through amplification of a selected gene sequence.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Polymerase chain reactions (PCR) are a powerful tool in molecular biology that allows for the amplification of specific DNA sequences. By targeting a selected gene sequence, PCR can detect the presence of an infection even before the body has produced antibodies. This is because PCR directly amplifies the genetic material of the pathogen, providing an early and sensitive method for diagnosis. Therefore, the given statement is true.

    A human product that is being made in genetically engineered microorganisms includes

    • Human growth hormone.

    • Insulin.

    • Tissue plasminogen activator.

    • Clotting factor VIII.

    • All of the above.

    Correct Answer
    A. All of the above.
    Explanation
    The correct answer is "all of the above." This means that genetically engineered microorganisms are used to produce all of the mentioned human products, including human growth hormone, insulin, tissue plasminogen activator, and clotting factor VIII. These microorganisms are modified to produce these specific proteins, which can then be harvested and used for medical purposes.

    What is a restriction fragment length polymorphism (RFLP)?

    • A sequence of DNA complementary to a mRNA molecule

    • A variation in length of DNA fragments due to inherited differences in proteins produced

    • A variation in length of DNA fragments due to random differences in proteins produced

    • A variation in length of DNA fragments due to inherited differences in highly repetitive DNA

    • A variation in length of DNA fragments due to random differences in highly repetitive DNA

    Correct Answer
    A. A variation in length of DNA fragments due to inherited differences in highly repetitive DNA
    Explanation
    A restriction fragment length polymorphism (RFLP) refers to a variation in the length of DNA fragments that is caused by inherited differences in highly repetitive DNA. These differences can be detected by using restriction enzymes to cut the DNA into fragments and then analyzing the resulting fragment sizes. By comparing the fragment sizes between individuals, it is possible to identify genetic variations and determine if they are associated with certain traits or diseases.
