All of the following are true about regulons EXCEPT:
|
They can be under positive or negative control. |
||
|
They control operons as well as sets of individual genes that are required to be expressed at the same time. |
||
|
They are present in prokaryotes and eukaryotes. |
||
|
Is how large groups of genes are globally regulated. |
Homework Answers
Ans. Regulons refers to a group of noncontiguous genes controlled by the same regulatory genes. It is termed exclusively for the gene regulation in eukaryotes. In prokaryotes the gene regulation is done by functional DNA unit consisting of several genes regulated by a common promoter and a common operator and is termed as Operons.
Hence, the answer is 'They are present in prokaryotes and eukaryotes'.

Both prokaryotes and eukaryotes: A. exhibit both positive and negative control. B. have repressors that impact expression.

the answer I gave was wrong
Which of the following statements about gene regulation concerning operons is INCORRECT? A regulator gene has its own promoter and is transcribed into an independent mRNA. For an operon under negative repressible control, a correpressor is required for the repressor to bind to the operator. Presence of operons where genes of related functions are clustered is common in bacteria but not in eukaryotes. For a gene under positive repressible control, the normal state is...

1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...
