Explanation:
Eukaryotic mRNA are monocistronic which are transcribed from a single gene and thus carry single initiation and termination codons there by coding for a single polypeptide.
A eukaryotic cell has a nucleus, surrounded by the nuclear membrane. There are other membrane systems|
in their cells, such as endoplasmic reticulum, Golgi apparatus, and vacuole.
- Expressed sequences of eukaryotic genes are exons.
- Process of removal of introns and joining of exons in defined order is splicing.
Two different modes of splicing have been defined, that is, constitutive splicing and alternative splicing. Constitutive splicing is the process of removing introns from the pre-mRNA, and Joining the exons together to form a mature mRNA.
