On this World Meteorological Day, celebrated each year on March 23, we climb far above the Earth for a view of the southern Peruvian coast courtesy of the Landsat 8 satellite. Below the clouds, at the bottom of those canyons, are the Yauca and <span>Acarí </span>Rivers, which drain into the Pacific. As any good meteorologist taking a break from today’s celebrations will tell you, warm air from the equator forms a layer over the cool coastal air here, pushing the clouds into the deep river canyons and covering the Pacific Ocean shore.
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
