An event that occurs after $RNA$ is transcribed

Vedclass · Answer

(A) $RNA$ processing (also known as post-transcriptional modification) is a series of events that occur after the transcription of $RNA$ from $DNA$. In eukaryotic cells,the primary transcript (pre-$mRNA$) undergoes several modifications before it is exported from the nucleus to the cytoplasm for translation. These modifications include: $1$. $5'$-capping: Addition of a $7$-methylguanosine cap to the $5'$ end. $2$. Polyadenylation: Addition of a poly-$A$ tail to the $3'$ end. $3$. Splicing: Removal of non-coding introns and joining of coding exons. Therefore,$RNA$ processing is an event that occurs after $RNA$ is transcribed.

$RNA$ processing is:

What is correct for bacterial transcription?

During transcription,the $DNA$ strand with $3' \rightarrow 5'$ polarity of the structural gene always acts as a template because

Assertion: The transcription and translation can be coupled in bacteria.
Reason: In bacteria,since the $\text{mRNA}$ does not require any processing to become active,and also since transcription and translation take place in the same compartment.

Compare the statements $A$ and $B$.
$Statement A$: $RNA$ produced during transcription in eukaryotic cells cannot be straight away used in translation.
$Statement B$: $RNA$ splicing phenomena helps in the removal of exons.
Choose the correct description.

$A$: All types of $RNA$ are synthesized by $DNA$.
$R$: All three types of $RNA$ are important in protein synthesis.
