Place the Polymerase Chain Reaction events listed below in the order in which they occur. - Double-stranded DNA is produced - DN
Contact [7]

Answer:

1- Test tube with DNA sample is placed in machine

2- DNA sample is heated

3- DNA denatures

4- Taq polymerase initiates DNA synthesis

5- Double-stranded DNA is produced

Explanation:

The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).

A sample of gold (AU) has a mass of 57.01 g.
Kamila [148]

A). Calculation: Given mass of Au * 1mol of Au/molar mass of Au= # of moles ;

57.01 g Au*1 mole of Au/196.97g Au=0.3 moles of Au.  So the answer is 0.3 moles of gold(Au). Good luck on the rest,  and message me on Brainly if you need more help. I'll be happy to.
