The conversion of the initial primary transcript synthesized by RNA polymerase II into a functional mRNA. What are the three major events that occur during the processing of Eukaryotic pre-mRNA? 5' capping, 3' cleavage and polyadenylation, and RNA splicing.

MRNAs have three parts: Nucleotides at the 5? end provide binding sites for proteins that initiate polypeptide synthesis; nucleotides in the middle specify the sequence of amino acids in the polypeptide; and nucleotides at the 3? end regulate the stability of the mRNA (Fig. 1.1).

During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.

Stages of Transcription Initiation. Transcription is catalysed by the enzyme RNA polymerase, which attaches to and moves along the DNA molecule until it recognises a promoter sequence.Elongation.Termination.5' Capping.Polyadenylation.Splicing.

(tran-SKRIP-shun) In biology, the process by which a cell makes an RNA copy of a piece of DNA. This RNA copy, called messenger RNA (mRNA), carries the genetic information needed to make proteins in a cell. It carries the information from the DNA in the nucleus of the cell to the cytoplasm, where proteins are made.

Transcription, as related to genomics, is the process of making an RNA copy of a gene's DNA sequence. This copy, called messenger RNA (mRNA), carries the gene's protein information encoded in DNA.

Transcription is a process of making an RNA strand from a DNA template, and the RNA molecule that is made is called transcript. In the synthesis of proteins, there are actually three types of RNA that participate and play different roles: a.

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein

While most genes are associated with multiple transcripts, each transcript is only assigned to a single gene (at least in databases). In other words, different genes never share the same transcript.

Three major events constitute pre-mRNA processing: (a) 5?-end capping, (b) splicing, and (c) 3?-end polyadenylation.
