It is known as Tower Triangulation. Hope this helps! :)
heh when you get the answer let me know cause im wondering the exact same thing
Answer:
The correct answer would be 5' capping, 3' polyadenylation , and intron splicing.
In eukaryotes, transcription results in the formation of pre-mRNA which needs to be processed in order to become mRNA (messenger ribonucleotide).
The pre-mRNA processing include:
- Addition of 5'cap (usually modified guanine nucleotide) at the 5'-end of the RNA. It prevents the RNA degradation and also help in the attachment of ribosome for translation.
- Addition poly-adenine (poly-A) tail at the 3'-end of the RNA. It increases the stability of the RNA and helps in its export out of the nucleus.
- Lastly, splicing takes place which removes the introns and joins the exons. Alternative splicing can also take place in order to produce many mRNA from a single gene.
Transcription and splicing only occur in eukaryotic cells. Transcription and splicing both occur in the nucleus.
Explanation:
Transcription is mediated by RNA polymerases that transcribe the DNA into RNA. In eukaryotes, because coding regions (exons) on the DNA are occasionally interspersed with non-coding regions (introns), the formed RNA (usually called nascent RNA) need to be spliced to remove the non-coding parts. This forms a mature messenger-RNA. All this occurs in the nucleus of eukaryotic cells and only after the mature mRNA is formed is it exported to the cytosol for translation into proteins by ribosomes.
Splicing does not occur in prokaryotic cells because their genome is all composed of coding regions. Therefore transcription on DNA produces, directly, a mature mRNA.
