Parts A-C in the table show the genotypes for two partial diploid strains of the lac operon. Gene names have been simplified (i.e., LacZ is shown as Z). Alleles are shown using superscript notations. There are two copies of the operon, one line is the copy in the genome and the other line is in a plasmid. In the blanks, indicate the effect of the partial diploid strains' genotype on the expression of the structure gene specified in the header of the table. Choose "functional" if you expect that any amount of normal enzyme will be made, "nonfunctional" if you expect that transcription occurs but only the mutated enzyme is made, or "no transcription" if the structural gene is not transcribed. Assume glucose is absent. Genotype (A) (B) (C) I- P+ O+ Z+Y- I+ P+ O+ Z- Y+ I- P+ OC Z+Y- I+ P- O+ Z-Y+ IS P+O+ Z+Y- I+ P+ OC Z- Y+ Lacy Presence of Lactose? 1. [Select] 3. [Select] 5.

The required association of two α-globin molecules and two β-globin molecules to make a functionally active hemoglobin molecule is an example of     translational control.     post-transcriptional control.     post-translational control.     chromatin control.     transcriptional control.

True or False: In eukaryotes, some parts of the RNA sequence transcribed by RNA polymerase are cut out before the final MRNA product leaves the nucleus. O True O False

Hi I'm not sure how to do this. Can you help? I'll leave a good review. thanks in advance!
