  • Q1

    Through genetic engineering, scientists developed a new technology that combines two different fragments of DNA from two different organisms to create new targeted trait, what is this new technology?

    Genetic Engineering

    Spliced Gene Technique

    DNA recombinant technology

    Genetics Cut

  • Q2

    The process of changing or altering the genes maybe summarized in four basic steps, which among the following steps come first?

    Cut the specific part of the DNA through a special enzyme

    Introduce the new formed DNA to the host cell

    Combine the DNA from two different sources

    Isolate the DNA from the cell and identify the target part of the DNA

  • Q3

    The second basic step to genetic engineering is:

    Target the special gene of interest and dissolve in saltwater

    Target specific part of the DNA and let RNA translates it

    Target the specific part of the DNA to be cut bya specialized enzyme

    Target specific part of the DNA and cut it into three

  • Q4

    The third basic step in genetic engineering is the process of combining fragments of DNA from different sources, this process may also be called:

    Gene combination

    Gene splicing

    Gene therapy

    Gene recombination

  • Q5

    Once the new DNA, is formed, which is a combination of fragments of DNA from different sources, it is already termed as:

    Recombinant DNA

    Genetically modified cell

    DNA molecule

    Organic Compound

    60s
  • Q6

    Lastly, the new DNA produced through genetic engineering will be introduced to a host cell to see how it will code for a new protein. What concept in biology is highlighted in this step?

    Law of inheritance

    Central Dogma of Molecular Biology

    Law of conservation of energy

    Central Atom of Molecules

  • Q7

    Living cells follow a specific hierarchy of command in directing the traits of the individual. What will happen to the new individual cell as a new engineered DNA was introduced to it?

    It will be destroyed as a new load of information is unhealthy.

    It will function according to the new set of codes from the DNA.

    It will try to mimic its environment in order to survive.

    It will have a different shape to adjust to the new code
