Answer:
The correct answer is - option e.)
Explanation:
The experiment that was performed by Meselson and Stahl was created to prove that DNA replication is a semiconservative process.
When Bacteria grow on 15N media they incorporate the isotype of nitrogen and after few generations, the culture moved to 14N media where it incorporates as they replicate in semi-conservative mode and one DNA strand comes from the Parent DNA.
The right option for question one is Option (e) Run as one band, at a position expected for DNA containing a 14N:15N ratio equal to 1.
The best answer to the question states above is letter C.<span> A short observation period.
</span>
<span> A scientist's primary concern in a clinical trial is the patient's safety, there fore short observation </span><span>decreases the reliability of results from a clinical trial</span>
Answer:
- production of vaccine for disease prevention
- production of genetically modified crops
Explanation:
Recombinant DNA is a special type of DNA that has been infused with a foreign gene of particular interest.
With recombinant DNA technology, scientists can study different proteins and see how they can be used for therapy in the area of medicine. <em>The technology has been used to produce several vaccine in the prevention of diseases.</em>
In addition, recombinant DNA technology has been useful in agriculture to produce <em>genetically modified crops with desired traits such as resistance to pests/diseases and high yields.</em>
Answer: It can rot your teeth out because of the stomach acid.
Explanation:
The correct answer is (B) False.
There is not as much energy used to add a phosphate group by means of phosphorolysis, as the energy required adding a phosphate using ATP.
What is Phosphorolysis?
- Glycogen phosphorolysis is a process that occurs at the start of glycogen breakdown. As a result, glucose can be produced from glycogen.
- Glycogen phosphorolylsis catalyzes glycogen phosphorolytic cleavage, resulting in glycogen-1-phosphate.
- However, when cleaving glucose from glycogen, a non-reducing terminal is eliminated.
- Furthermore, phosphoglucomutase can convert glucose-1-phosphate generated from glycogen into G6P, allowing it to go directly to glycolysis.
- It should be noted that going straight to glycolysis eliminates the need for ATP to convert glucose to G6P.
- If the glucose created by glycolysis is consumed, three ATPs are produced.
- Phosphorolysis requires less energy than ATP to add a phosphate group.
