Mean of 200 observations was found to be 90. However, when the observations were being made, two observations were wrongly taken as 15 and 80 instead of 40 and 87. Then the correct mean is

is the process by which that genetic material is passed on. Any mistake that arises during _II_can therefore easily be catastrophic, it becomes permanent in the genome of that individual and gets passed on to subsequent generations.

_I_, in contrast to _II_ produces only transient copies and normally several from each transcribed region. Thus, a mistake during III will rarely do more harm.

Some more DNA-dependent RNA polymerases have been identified in recent years, These are found only in plants, where they transcribe small interfering RNAs involved in transcriptional silencing;

Which DNA-dependent RNA polymerases  are closely related to Pol II and clearly evolved from that enzyme relatively recently, some of their subunits are identical to those from Pol II, encoded by the same genes, and the others are from recently duplicated copies;
