What is the function of the following elements of an operon? a) regulator b) operator c) promoter d) structural genes Operon: Operon is a structure in DNA and contains multiple functional genes. Prokaryotes
What does the lac operon consist of?Lac Operon:The lactose operon (also called the lac operon) is a group of genes present in E. coli and other bacteria responsible for lactose absorption and metabolism. Two proteins regulate the activity of the lac promoter, which controls the lac operon's...
1) What is an operon, and what kinds of cells use operons? 2) What is a repressor protein, how does it regulate the transcription of an operon (like the lac operon)? Define operon. Explain the operon with its components. What is an operon? In what type of organism would you expect...
Do all organisms have introns? What does transcription do in protein synthesis? What molecule is produced by RNA polymerase during transcription? What are the patterns of DNA structure? What is the role of the promoter in terms of the repressor, the operon, and the operator, in a bacterial...
The enzyme RNA polymerase is an essential part of the cellular machinery that translates the genetic code in the DNA into mRNA as an intermediate step in the production of cellular proteins.Answer and Explanation: RNA polymerase malfunctions could be fatal to the cell since this enzyme is ...
When does the replication of DNA occur?Describe the process of DNA replication.What is helicase? Describe its role in DNA replication.What would happen if there was a mutation in the operator of the trp operon?What is the difference between plasmid replication and chromosomal replication?
Why does an operon contain only one promoter? What is the part of the gene that is the on/off signal? A) termination sequence B) promoter C) coding region D) trick question, genes do not need to be signaled to turn on or off. Every gene is always turned on in every c...
In general terms, what are the two factors required to activate gene transcription? Gene Transcription: DNA replication is the process by which the genetic material of the organism copies itself to be distributed among the daughter cells during cell division. DNA replication takes pla...
B. They break down and absorb lactose, thereby depriving the bacteria in the colon of lactose as an energy source. C. What kind of protein is lactase, the biomolecule that speeds up the breakdown of lactose? How does lactose (allolactose) regulat...
When E. coli is in an environment that contains no sugar, what is happening at the operator/promoter for the lactose operon? What product will result from complete hydrolysis of soluble dextran? Which of the following is not a component of a nucleotide? A. Sugar...
