This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × $10^{-12}$ N

displacement = 8.0 nm = 8.0 × $10^{-9}$ N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × $10^{-12}$ × 8.0 × $10^{-9}$ = 64 × $10^{-21}$

= 6.4 × $10^{20}$ Joules (in standard form)

Why is RNA polymerase a good name for the enzyme that carries out transcription

KATRIN_1 [288]

Answer:

RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.

Explanation:

RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .

one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.

RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.
