During RNA synthesis, specifically during the process of transcription, introns are transcribed along with exons in the precursor mRNA (pre-mRNA). However, before the mRNA is translated into protein, introns are removed through a process called splicing, which occurs in the nucleus. The remaining exons are then joined together to form the mature mRNA that exits the nucleus and is translated into a protein. This splicing process ensures that only the coding sequences (exons) are included in the final mRNA product.

Does RNA have introns?

Yes, RNA does not have introns.


Are exons or introns spliced out during the process of RNA splicing?

During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.


What is removed from pre-mRNA during RNA processing?

In RNA processing, introns are removed from pre-mRNA to generate mature mRNA. Introns are non-coding regions of the pre-mRNA that do not contain instructions for protein synthesis. The remaining exons are spliced together to form the mature mRNA that can be translated into a protein.


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.


What are the codes for proteins is it exons or introns?

The codes for proteins are found in the exons of a gene. Exons are the coding regions of a gene that are transcribed into mRNA and translated into proteins. Introns, on the other hand, are non-coding regions that are spliced out during RNA processing and do not contribute to protein synthesis.


Why are introns copied and then removed from the RNA sequence?

Introns were copied and then removed from the RNA sequence because they were placeholders.


WHAT DOES During protein synthesis messengers RNA?

Messenger RNA molecules are fed through the ribosomes during protein synthesis.


How do introns and exons relate to RNA splicing?

Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called RNA splicing.


What is the process called which removes introns from RNA?

RNA splicing


Spliced together during mrna processing?

Exons, after the introns have been cleaved.


What are portions of rna that are cut out and discarded?

Does a codon catalyze rna synthesis?

No, a codon does not catalyze RNA synthesis. Codons are sequences of three nucleotides in mRNA that correspond to a specific amino acid during translation. RNA synthesis is carried out by an enzyme called RNA polymerase.
