Question

the function of beta subunit of polymerase is which binding? 1- template binding,2-catalytic binding,3-promoter binding,4-cation binding​

Answer 1

Answer:

Explanation: The β' subunit of polymerase binds to two Zn2+ ions which are thought to participate in the catalytic function of the polymerase. It is also responsible for the binding of the enzyme to the template DNA.

Answer 2

Answer:

The correct option is 2 , catalytic binding.

Explanation:

• A transcription start site is mainly associated with the β' subunit, while the β chiefly confers the catalytic activity. Alpha subunits interact with regulatory proteins while sigma subunits provide specificity.

• It is thought that the beta(β) subunit of polymerase participates in polymerase's catalytic function by binding to two Zn2+ ions. It is also responsible for the enzyme's binding to template DNA.
