Restriction enzyme EcoRI always cleaves the nitrogen sequence in DNA
A genetically engineered bacteria used for clearing oil spills is
Reporter genes
Rennin used in cheese industry is
Restriction endonucleases
The primary reason why the same basic techniques can be used to analyze the DNA from species as diverse as bacteria and humans is that
The fact that DNA is structured the same way in all known organisms means that similar methods can be used to study the hereditary material.
Which of the following is a critically important tool used in experiments involving DNA hybridization?
DNA probes are specially constructed sequences that are complementary to the target sequence in the sample being tested. The probes bond (hybridize) with the target sequence wherever it occurs in the DNA sample.
A gene is said to be cloned if
Although cloned genes may be used as part of, or in association with, the other choices, the definition of a cloned gene is one that has been isolated and repeatedly duplicated.
Product of biotechnology is
To study the genetic basis of the inherited human disease sickle-cell anemia, a biologist must first isolate DNA from an affected individual’s cells. The next step is to use
Once isolated, DNA can be cut into fragments using restriction enzymes. The other choices involve methods used after the restriction fragments have been generated.
