RNA capping occurs co-transcriptionally in the nucleus of eukaryotic cells. As RNA polymerase II synthesizes the pre-mRNA, the 5' end of the nascent transcript is modified by the addition of a 7-methylguanylate (m7G) cap. This modification plays a crucial role in mRNA stability, export from the nucleus, and translation efficiency.
Before messenger RNA (mRNA) is mature, it undergoes several post-transcriptional modifications. These modifications include capping, splicing, and polyadenylation. Capping involves adding a modified guanine nucleotide at the 5' end, splicing removes introns to create a mature mRNA sequence, and polyadenylation adds a poly-A tail at the 3' end.
The three main ways mRNA strand is modified are 5' capping, 3' polyadenylation, and RNA splicing. 5' capping involves adding a modified nucleotide at the 5' end to protect the mRNA from degradation. 3' polyadenylation involves adding a string of adenine nucleotides at the 3' end to stabilize the mRNA and regulate its translation. RNA splicing is the removal of non-coding regions (introns) and joining of coding regions (exons) to form a mature mRNA molecule.
A cap is associated to the 5' end of mRNAs of TMV transcribed by PolyII , which is essential for recruiting translation initiating factor and for anchoring RNA of the actin/endoplasmic reticulum (ER) network.
The final step of transcription is the termination of RNA synthesis, where the RNA polymerase enzyme reaches a specific termination sequence in the DNA template. This signals the end of the gene, prompting the RNA polymerase to detach from the DNA and release the newly synthesized RNA molecule. The RNA undergoes further processing, such as capping and polyadenylation, before it is ready for translation.
After transcription ends, the newly synthesized RNA molecule undergoes processing. In eukaryotes, this includes capping at the 5' end, addition of a poly-A tail at the 3' end, and splicing to remove introns. The mature mRNA is then transported from the nucleus to the cytoplasm, where it can be translated into proteins. In prokaryotes, the process is more direct, as transcription and translation can occur simultaneously without extensive RNA processing.

In the ribosomes.
mRNA processing is a series of modifications that occur to a primary RNA transcript (pre-mRNA) before it is translated into a protein. This process includes capping, splicing, and polyadenylation to produce a mature mRNA molecule that can be effectively translated in the cell.
the types that occur are complementary and antiparallel. For example, DNA A will pair with RNA U and DNA C will pair with RNA G.
yam capping is the name given to the covering part of the root.

The mRNA produced by transcription is similar to a rough cut of a film that needs a bit of editing. A specialized nucleotide is added to the beggining of each mRNA molecule, which forms a cap. It helps the mRNA starand bind to a ribosome and prevents the strand from being broken down to fast. The end of the mRNA molecule gets a string of A nucleotides, called the tail, that helps the mRNA molecule exit the nucleus.
Yes, they [both] do. In particular, nuclear Rna synthesis takes place in the Nucleoli.
