Question

what is post transcriptional modification?​

Answer 1

Post transcriptional modifications are changes that occur to a newly transcribed primary RNA transcript (hnRNA) after transcription has occurred and prior to its translation into a protein product.

Hope it will help you.

Answer 2

Primary transcript made by RNA polymerase normally undergo further alteration , called post transcriptional modification .

▪️ Prokaryotes mRNA transcribed directly from DNA template and used immediately in Protein synthesis .

▪️ Eukaryotes : primary transcript (hnRNA) must be the process to produce the mRNA (active from)

▪️it occures in nucleus of cell .
