In bacteria, a mutation in the could influence rna polymerase binding, and a mutation in the could influence repressor binding. a. b. c. d.

In bacteria, a mutation in the promoter could influence rna polymerase binding, and a mutation in the operator could influence repressor binding.

Option D

Explanation:

The transcription process is an ideal process that helps in the production of the RNA by using DNA with the help of the RNA polymerase enzyme, the sequence of the DNA to which the RNA polymerase enzyme binds initially is termed as the promoter whereas the operator is the sequence that influences the binding of the gene repressor proteins.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
