Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

Part A Which of the following features is a significant difference in the function of DNA polymerases versus RNA polymerases? Se
Artist 52 [7]

Answer:

The correct answer is RNA polymerase does not require a primer to add new nucleotides.

Explanation:

RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.

   RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.
