Answer:
The correct answer is - option e. uses ATP as a substrate.
Explanation:
Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.
ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.
In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.
Sucrase. Sucrase is secreted by the small intestine, where it breaks down sucrose (the sugar in table sugar) into fructose and glucose. These are simpler sugars that the body can absorb.
Answer:
See below
Explanation:
A hypothesis theory and a scientific law are starkly different terms. A hypothesis is at a stage where it is tested in a way that either proves it right or wrong. In the case that it is proved right, it goes on further to be replicated by a several other groups of scientists. If the results/conclusions come out to be correct again, it is known as scientific theory - a more detailed explanation for some phenomenon. Further on, this theory will achieve the status of a scientific law when it has been studied in sufficient detail to give a unifying concept about the phenomenon.
I believe its D. An experiment that reveals a new step in a metabolic pathway.
Hope this helps! ;)
