Given below are two statements regarding RNA polymerase in prokaryotes.
Statement I : In prokaryotes, RNA polymerase is capable of catalysing the process of elongation during transcription.
Statement II : RNA polymerase associate transiently with ‘Rho’ factor to initiate transcription.
In the light of the above statements, choose the correct answer from the options given below :
Statement I : In prokaryotes, RNA polymerase is capable of catalysing the process of elongation during transcription.
Statement II : RNA polymerase associate transiently with ‘Rho’ factor to initiate transcription.
In the light of the above statements, choose the correct answer from the options given below :
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
The Correct Option is A
Solution and Explanation
Statement I: Prokaryotic RNA polymerase is responsible for the elongation phase of transcription. Correct
Statement II: The Rho factor is involved in termination, not initiation of transcription. RNA polymerase interacts with sigma factor (σ) for initiation and with Rho factor (ρ) for termination. Incorrect

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)

- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell.
Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus.- NEET (UG) - 2025
