Homework Answers
Related genes like Operon is a cluster of genes which work under a common promoter. These genes are found in a cluster on chromosome.
RNA polymerase binding site acts a single promoter. Like lac operon gene contains genes Z, Y ,A. Which forms galactosidase, permease, and transacetylase.
Transcription is DNA to RNA .. it is regulated so as to prevent or increase transcription..and regulate gene expression. It is a vital process in all living organisms
DNA replication is carried out with high fidelity, so that the genetic information may get transfer correctly from one generation to generation. Proofreading activity is done byDNA polymerase III, which checks the attachment of the nucleotides to the correct base pair. mismatch found between the base pairing of the complementary bases is also corrected.
Transcription occurs in cytosol and fidelity is not important as discussed above.
.
Non coding ncRNA are not translated . They include miRNA, piRNA, siRNA.

Why are related genes transcribed together? Why is transcription regulated? RNA Polymerase does not have proofreading...

In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....

Why does E. coli have several different sigma factors? A.They allow RNA polymerase I, RNA polymerase II and RNA polymerase III to bind to different promoters. B.They allow the different subunits of the RNA polymerase holoenzyme to bind to each other. C.They are redundant in case one is mutated. They all perform the same function. D.One is needed to transcribe mRNA. A second is needed to transcribe tRNA. And a third is needed to transcribe rRNA. E.They are used if...
