DNA polymerase may be defined as the enzyme that are responsible for the synthesis of the DNA molecule. Single DNA polymerase is present in prokaryotes whereas three different DNA polymerase is present in eukaryotes.
The DNA polymerase has the ability to break the phosphodiester bond and can detect the incorrect match pair and plays an important role in the DNA repair process. This enzyme has the ability to acts as an exonuclease as well. The polymerization reaction cannot be reversed by the DNA polymerase and other specific enzymes require for this process.
The area representinf the cone-rich fovea is much larger than one would expect from the fovea's small size. The cortical magnification factor in the human cortex has been determined using a technique called brain imaging, which makes it posible to create pictures of the brain's activity.
In this theory, gas molecules are deemed to be at constant random motion and have perfectly elastic collisions with each other. They bounce of each other. These particles are assumed to have a spherical shape. Also, there are no attractions between the molecules.<span />
