Question:
Which factor is important for termination of transcription?
Which factor is important for termination of transcription?
Show Hint
Rho ($\rho$) = Termination. \quad Sigma ($\sigma$) = Initiation.
Updated On: May 4, 2025
- $\sigma$ (sigma)
- $\rho$ (rho)
- $\gamma$ (gamma)
- $\alpha$ (alpha)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The rho ($\rho$) factor is a protein involved in the termination of transcription in prokaryotes. It binds to specific sequences in the newly synthesized RNA and acts as a helicase to unwind the DNA-RNA hybrid, leading to the release of the RNA polymerase and termination of transcription. Sigma factor is involved in initiation, not termination.

- The blue and white selectable markers have been developed which differentiate recombinant colonies from non-recombinant colonies on the basis of their ability to produce color in the presence of a chromogenic substrate. Given below are two statements about this method: Statement I: The blue-colored colonies have DNA insert in the plasmid, and they are identified as recombinant colonies. Statement II: The colonies without blue color have DNA insert in the plasmid, and are identified as recombinant colonies.

In an oscillating spring mass system, a spring is connected to a box filled with sand. As the box oscillates, sand leaks slowly out of the box vertically so that the average frequency ω(t) and average amplitude A(t) of the system change with time t.

- Two identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is \(q\) and the force of repulsion between them is \(F\). A third identical uncharged conducting sphere C is brought in contact with sphere A first and then with sphere B and finally removed from both. New force of repulsion between spheres A and B (Radius of A and B are negligible compared to the distance of separation so that they can be considered as point charges) is best given as:
