Which of the following is INCORRECT when considering the lac repressor?

Binding to the operator site is cooperative.

It is tetramer of two dimers.

It is an allosteric protein.

Binding of inducer forces the DNA-binding helices apart so they cannot contact the DNA-binding sites.

Binding of each dimer is to different regions of the operator.

Expert Solution

Binding to the operator site is cooperative.

Explanation:

Repressor prevents the activity of the operator in the lac operon. The repressor protein prevents transcription by binding to lac operator.

Which of the following is INCORRECT when considering how to identify the successful incorporation of a DNA insert into a vector? A. Colony PCR indicates the presence and size of an insert B Ampicillin resistance indicates the presence of an insert C Blue/white screening indicates the presence of an insert D DNA sequencing confirms the identity of a correct insert A mutation in the iron response element (IRE)-binding protein causes it to have a much higher affinity for the IRE...

Which statement is NOT true about the repressor protein, in regard to the lac operon: Group of answer choices it blocks transcription when it is bound to the operator is only expressed when glucose is present it changes its three-dimensional shape (conformation) when it is bound to the inducer, allolactose All listed ARE true about the repressor binds to the operator region of the lac operon when glucose is being utilized

Mutations on the Lac repressor may result in the lac operon never being induced all the choices are correct result in the repressor binding the operator even in the presence of the inducer result in the inducer not being able to bind the repressor result in constitutive expression of the lac operon

please answer all of them The map of the lac operon and repressor gene is presented here: I POZYA P is the promoter; O is the operator; Z encodes ß-galactosidase; Y encodes lactose permease; A encodes a transacetylase. The genotypes of merodiploids are shown below. For each one, choose the correct phenotype from the table below. (The same phenotype can be chosen for more than one genotype) PHENOTYPE ß-Galactosidase No lactose with lactose A) - + B) - - C) + + D) + - I--P+O+Z+/I+P--O+Z-- Select one: a. A b. B...
