RNA is spliced (cut) in order to make it mature. This involves splicing out the introns and leaving the exons - these are the segments that code for a protein.

This means that when mRNA leaves the nucleus, it only contains the segments that directly code for a protein.

What happens before messenger RNA is mature?

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.


What are the intervening sequence of RNA molecules that are cut out before the messenger RNA leaves the nucleus?

The intervening sequences of RNA molecules that are cut out before the messenger RNA leaves the nucleus are called introns. These introns are non-coding sequences that are spliced out of the pre-mRNA during the process of RNA splicing, leaving only the exons to form the mature mRNA that is then transported to the cytoplasm for translation.

Which happens first messager RNA or transfer RNA?

Messenger RNA (mRNA) is synthesized during transcription in the nucleus before transfer RNA (tRNA) comes into play during translation in the cytoplasm. So, mRNA is produced first in the sequence of events.


Which one exons or introns is spliced out when primary RNA is processed?

The introns are the sections which are spliced out to create the mature form of mRNA.


RNA that is a copy of DNA message that can enter the cytoplasm?

Messenger RNA (mRNA) is a copy of the DNA message that is transcribed in the nucleus and can be translated into proteins in the cytoplasm. It carries the genetic information from the DNA to the ribosomes where protein synthesis occurs.

What is RNA processing?

1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.


What is the form of RNA that carries the code from the DNA to the site where the proteins is assembled?

The mRNA carries information to the ribosomes. This is known as 'messenger' RNA because it carries the message, the base sequence from the nucleus to the ribosome. This mRNA is then translated into an amino acid sequence (polypeptide/protein) at the ribosome.


In eukaryotic cells the mRNA is processed and migrates from the to the .?

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.


What is The type of RNA that carries information from DNA to the ribosome of a cell is known as?

The type of RNA that brings instructions from DNA in the nucleus to the cytoplasm is messenger RNA or mRNA.
