In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre-mRNA. This pre-mRNA undergoes processing, including the addition of a 5' cap, a poly-A tail, and splicing out introns, resulting in mature mRNA, which …
Once they're loaded up with the right amino acid, how do tRNAs interact with mRNAs and the ribosome to build a brand-new protein? Learn more about how this process works in the next article, on the stages of translation.

Post-transcriptional regulation occurs in eukaryotes, stabilizing mRNA for translation. DNA transcribes into RNA, with exons coding for proteins and introns removed by spliceosomes. The mRNA acquires a 5' prime cap and 3' prime poly-A tail for protection and translation promotion.
This type of RNA is called a messenger RNA (mRNA), as it serves as a messenger between DNA and the ribosomes, molecular machines that read mRNA sequences and use them to build proteins. This progression from DNA to RNA to protein is called the “ central dogma ” …
mRNA processing Once RNA polymerase is done, the mRNA transcript has to be processed before it can make its journey out of the nucleus and to the ribosome. Processing has two phases: protection and splicing.
