you could chose to describe the first graph as any of the following phrases:
‘curved graph’
‘intercept on y-axis’
‘as x increases, y increases’,
‘y increases slowly at first, then more rapidly, then slows down again’ and ‘reaches a maximum level’.
you can chose to describe the second graph as any of the following phrases:
'gradually increases, then rapidly increases in a short period of time"
The enzyme Taq polymerase is required in the PCR process because it is the main enzyme that synthesizes the new DNA strands complementary to the template strand and without the activity of this enzyme the PCR will be useless and it cannot make the copy of the given strand in any way. Thus, this enzyme is very much necessary for the efficient working of the PCR.
Polymerase Chain Reaction is a very efficient technique that can able to detect and copy even a small amount of DNA by performing a set of reactions at different temperatures.
The PCR process begins with the denaturing of the template strand at 95°C, followed by annealing in which the appropriate primers bind to the single strands of DNA at 50-56°C, followed by extension at 72°C in which the thermostable Taq polymerase synthesizes the strand complementary to the template DNA.
