Hii basically ive included a photo of what it should look like
Good luck!!
Mechanisms of Speciation New examples of sympatric speciation revive some nagging ... in Systematics and the Origin of Species in 1942, and that's how Mayr still sees it today. ... He remains quite seriously dedicated to his view of the world.
Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.

Explanation:
The evolution of photosynthetic organisms, about 4.9 bilion ago, changed the earth’s atmospheric composition. The photosynthetic organism took up most of the carbon dioxide and evolved oxygen. They are responsible for the Great Oxygenation Event.
As oxygen filled the atmosphere, it became possible for ozone (O₃) to form. In the upper atmosphere ultraviolet light rays split molecular oxygen into atomic oxygen ( through photolysis), and the oxygen atoms react with oxygen molecules (O₂) to form ozone (O₃). This is a forward and reverse reaction because the ozone also decomposed back to molecular oxygen.
The formation of ozone helped the colonization of land by life because ozone prevents most UV from reaching earth's surface and protected the genetic material from the ionizing effect of ultraviolet rays.
