What is the role of RNA polymerase III in the process of transcription in eukaryotes
- Transcribes only snRNAs
- Transcribes rRNAs (28S, 18S and 5.8S)
- Transcribes tRNA, 5s rRNA and snRNA
- Transcribes precursor of mRNA
The Correct Option is C
Solution and Explanation
RNA polymerase III is responsible for transcribing a variety of small RNA molecules, including transfer RNA (tRNA), 5S ribosomal RNA (5S rRNA), and small nuclear RNAs (snRNA), among others. It is not responsible for transcribing the precursor of mRNA, which is primarily the role of RNA polymerase II.
So, the correct option is (C): Transcribes tRNA, 5s rRNA and snRNA

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

DNA Replication
The process by which the genome’s DNA is copied in cells is called DNA Replication. It must first copy (or replicate) its entire genome before cell division so that each resulting daughter cell ends up with its own complete genome.
It is the natural cycle of creating two indistinguishable imitations of DNA from one unique DNA molecule. DNA replication happens to take all things together living creatures going about as the most core part for organic legacy. This is important for cell division during the development and fixation of harmed tissues, while it likewise guarantees that every one of the new cells gets its duplicate of the DNA. The phone has the unmistakable property of division, which makes replication of DNA fundamental.
The parental DNA stays together, and the recently shaped daughter strands are together in conservative replication. The semi-conservative strategy recommends that every one of the two parental DNA strands goes about as a format for new DNA to be integrated; after that each two-fold abandoned DNA incorporates one "old" strand (parental) and one "new" strand.
