Polymerase chain reaction (PCR) is a molecular biology technique  for enzymatically replicating DNA without using a living organism, such as E. coli or yeast. Like amplification using living organisms, the technique allows a small amount of DNA to be amplified exponentially. As PCR is an in vitro technique, it can be performed without restrictions on the form of DNA and it can be extensively modified to perform a wide array of genetic manipulations.
The amount of DNA is doubled each cycle
300 * 2 * 2 * 2 * 2 * 2 = 9600 g
Five cycles of the polymerase chain reaction is carried out on a double-stranded DNA section consisting of...?
...30 base pairs. If the average mass of a nucleotide is 300 g what is the mass of the DNA molecules at the end of the five cycles?
- How many moles of CO2 are produced when 3 moles of CH4 react with O2?
- The partial pressure of nitrogen in clean, dry air at 0 degrees C is 625 torr when the total pressure is 760 torr.?
- What are the other ions found in the solution KNO_3?
- Chemistry moles and molecules?
- I am trying to discover a new element. I shall call it Zinc?
- Do things in real laboratories actually go through spiral tubes?
- Was there a myth, that putting batteries in the freezer would recharge them? (AA and AAA alkaline batteries)?
- I have this assignment on antacid but I have found no balanced equation, I would truly much appreciate some help.?
- Do all chemistry teachers know how to make meth?
- How much heat is required to raise the temperature of 62.5 g of water from its melting point to its boiling point?
