DNA helicase unwinds DNA by breaking H bonds between DNA strands. DNA polymerase joins adjacent nucleotides by forming phosphodiester bonds between them.

We can find dz/dy using chain rule dz/dy=dz/du x du/dy (1) by defining u=3y^2+5 (since the exponent of e is a function of y we call this function u) and rewrite z=e^u. Then, we find dz/du=e^u (2) and du/d...

This function is fraction so the easiest method is to use the quotient rule (though the product rule can be used). Recall the quotient rule dy/dx = [vu' - uv']/[v^2]Note, u and v refer to the numerator a...

This is a topic that is becoming increasingly popular in both written and speaking French examinations. The basis for the structure of the answer can often be reapplied to a variety of topics including ce...

Oliver Cromwell has long been the subject of historical debate, particularly concerning his political actions and leadership style. Unquestionably, his main source of power was his military support base, ...
