- 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
60s - 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
60s - 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
60s - 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
60s - 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
60s - 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
60s - Q8
What application of Recombinant DNA technology is used by farmers in order to produce a better yield in crops, a better quality of crops, and easier pest control?
