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.
angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.
- Climate is simply an extended study of weather over a long period of time.
- The elements of weather like temperature, pressure, rainfall all conditions climate.
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

The component which would be found in a eukaryotic cell but not in a prokaryotic cell is the nucleus.
<h3>What is the difference between a eukaryotic and prokaryotic cell?</h3>
A eukaryotic cell is a cell that possesses a true nucleus surrounded by a nuclear membrane.
Examples of a eukaryotic cell is animal and plant cells.
A prokaryotic cell is a cell that lacks a true nucleus.
Examples of a prokaryotic cell is a bacterial cell.
Therefore, the components which would be found in a eukaryotic cell but not in a prokaryotic cell is the nucleus.
