are polymerases structural proteins?

Answer 1

Nope. Structural proteins are the proteins that help your cells maintain proper shape and rigidity. Once formed they generally do not possess enzymatic activity.

Polymerases are enzymes that help synthesize new strands of DNA or RNA (termed DNA- or RNA-polymerases, respectively). They have roles in genome duplication prior to cell division as well as gene expression, but do not have a direct role in maintaining cell structure.

Answer 2

All functional proteins, like polymerases, have structure. If the protein becomes denatured, it loses its structure and thus its function.
I think I misunderstood the question

Answer 3

polymerase is an enzyme whose central function is associated with polymers of nucleic acids such as RNA and DNA. The most well-known function of a polymerase is the catalysis of production of new DNA or RNA from an existing DNA or RNA template, a process known as polymerization. In association with a cluster of other enzymes and proteins, they take nucleotides from solution, and hydrogen-bond them to complementary nucleotides that are on the template, or sense strand.

It is an accident of history that the enzymes responsible for the catalytic production of other biopolymers are not also referred to as polymerases.

Answer 4

yes proteins have tertiary structures
