Answer 1

Answer #1

Option E. Both A and B.

The hairpin loop structure is followed by a string of U residues. This is seen in E.coli.

The termination signal after the gene is present in eukaryotes. This helps the Polymerase to identify the sequence.

Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

Transcription is terminated, when a characteristic RNA structure _____ is formed by local RNA palindromic sequences at the 3’- end. The structure interacts with RNAP-bound NusA, causing dissociation of RNAP from template DNA. The RNAP dissociation is stimulated by sequence-specific binding of _____ proteins to the transcribed RNA, enhancing termination of transcription. Select one: a. hairpin ;;;; rho b. hairpin ;;;; sigma c. beta-turn ;;;; rho d. beta-turn ;;;; sigma e. None of these

Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...
