Answer #1

CORRECT ANSWER: ACTIVE ACTIVATOR

EXPLANATION: FIRST WHAT IS OPERON ?

A group of genes that are transcribed together in a single mRibonucleic Acid.

A REPRESSIBLE OPERON: A operon that is transcriptionally active and must be turned off is called a repressible operon. In repressible operon under positive control, the protein produced by the regulator gene will be synthesized as active activator.

For the opposite of these in an inducible operon under positive control, the protein produced by the regulator gene will be synthesized as an inactive activator.

1.    The lac operon in E. coli comprises three structural genes, lac Z, lacY, and lacA. It is regulated by both positive and negative mechanisms, involving binding of both a repressor protein and the catabolite activator protein (CAP). Transcription of the operon gives a polycistronic mRNA encoding the three enzymes. Under the following nutritional conditions, indicate whether or not the repressor and the CAP are bound by drawing them in on the appropriate regions of the operon. Indicate, as well,...

3. Which of the following statements is TRUE? The regulatory proteins produced by the MATa and MAT? alleles are identical and are found in all three yeast mating types. Unlike the MATa allele, the MAT? allele can actually produce two proteins, ?1 and ?2, which function as an activator and repressor, respectively. In yeast cells, the Mcm1 protein is encoded by the MATa allele and as such is only present in a cells. The MAT gene is the only gene...

For this question, we focus on four parts: I, the gene that produces the repressor protein; P, the promoter region where RNA polymerase binds to initiate transcription; O, the Operator site, where the repressor binds. When the repressor binds, it prevents transcription; and ZYA, the three structural genes, all of which are required for the successful utilization of lactose as a food source. In the left column of the table below, we indicate the genetic composition at the lac operon...

The genome of the bacteriophage M13 was modified to include a CRISPR-Cas 9 operon with the following features: The operon includes a gene coding for protein Cas 9, and a gene coding a sgRNA. The CRISPR-Ca9 operon is under the control of a bacterial constitutive promoter. The sgRNA gene includes a spacer flanked by two repeats. The sequence of the spacer matches a sequence of an antibiotic resistance gene present in an antibiotic resistant form of a bacteria. Bacteria containing...
