The interactions of ligands with protein,

A ligand is

Assertion :- The activity of RNA polymerase at a promotor is regulated by interaction with accessory protein, which affect its ability to recognize start sites. Reason : The accessibility of promotor region of prokaryotic DNA is in many cases is regulated by interaction of proteins with operators.

The mechanism in which the rate of the solute movements increases by interaction of transmembrane proteins is termed as

The accessibility of promote regions of prokaryotic DNA by RNA polymerase is in many cases regulated by the interaction of some protein with sequences termed as -

Assertion :- The activity of RNA polymerase at a pormotor is regulated by interaction with accessory protein, which affect its ability to recognise start sites. Reason : The accessibility of promotor ragion of prokaryotic DNA is in many cases is regulated by interactin of proteins with operators.

In recent years, considerable attention is being given to DNA protein interactions because the expression of genes is regulated through banding of specific proteins on the regulatory DNA sequences. This pattern of protein banding on DNA ca be studied by
