Answer 2

enzyme

Answer 3

The gene is expressed with the assistance of a long array of intermediary enzymatic and nucleic molecules. So from this list enzyme makes the most sense.

A gene is first transcribed by RNA polymerase enzyme.
The mRNA is modified by an array of enzymatic machinery to the mature mRNA.
This mRNA is then translated by a ribosome assembly to produce the protein. While the ribosome is not a just a protein, it does have catalytic abilities.
