Predict the ways in which the following conditions will affect the transcription of the lactose-utilization genes. OPERON Regulatory Promoter Operator_ gene Lactose-utilization genes DNA mRNA RNA polymerase cannot attach to promoter Active repressor Protein If a mutation in the regulatory gene results in a misfolding of the repressor protein so that it can no longer bind DNA, the lactose-utilization genes O Will be...

The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...

these two answers would make sense. Thank you for the help!
Question 1 (1 point) Saved Why can bacteria have poly-cistronic genes? Because they need multiple cistron organelles so they segregate evenly during cell division. Because they have many exons that are joined together before translation Because ribosomes can be loaded at multiple Shine Delgano/AUG sequences. Because ribosomes are loaded at the single CAP site. Because the stability...

QUESTION2 Which of the following statements is TRUE? O DNADNA hybrids and RNADNA hybrids are always antiparallel O DNA is replicated using the template strand as the template but RNA is transcribed using the sense (or coding) strand as the template. O Both DNA and RNA polymerization require a primer O Introns get spliced out of DNA and out of pre-mRNA QUESTION 3 0. Which of the following statements is FALSE? O Only Eukaryote genes have an A/T rich core...

1. The map of the lac operon is P-O-Z-Y. The promoter (P) region is the start site of transcription through the binding of the RNA polymerase molecule before actual mRNA production. Mutationally altered promoters (P-) apparently cannot bind the RNA polymerase molecule. Certain predictions can be made about the effect of p-mutations, Use your knowledge of the lactose system to complete the following table. Insert a "4" where an enzyme is produced and a "_" where no enzyme is produced....

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
