Im not 100 percent sure, but I believe that the answer is D) because A), B), and C) are all equally necessary. Yet D) seems to have a much higher level of importance
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.
Answer:
In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate. Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old.
And that's how after rounding we know that earth is 4.5 years old.
Osteoporosis is the disease of the low bone mass and most often caused by the increase in the bone resorption that is not in sufficiently compensated for by the corresponding increase in the bone formation. As result gut-derived serotonin (GDS) inhibits the bone formation, we can asked whether hampering its is biosynthesis that could treat the osteoporosis through the anabolic mechanism (that is, by increasing bone formation).
We can synthesized and used the LP533401, a small of molecule inhibitor of the tryptophan hydroxylase-1 (Tph-1), the initial enzyme in the GDS biosynthesis. or the Oral administration of this small molecule once daily for up to the six weeks that acts as prophylactically or therapeutically, in the dose-dependent manner, to treat the osteoporosis in the ovariectomized the rodents because of an isolated increase in the bone formation. These results that provide a proof of the principle that have inhibiting the GDS biosynthesis that could become a new anabolic and treatment for osteoporosis.
