Pre-mRNA requires splicing … WebJan 17, 2024 · Pre. mRNA becomes mRNA after processing. Hence, it contains only the exons or coding sequences of the gene. Once made, mRNA travels away from the nucleus to the cytoplasm. In the cytoplasm, ribosomes read the base sequence of the mRNA and recruit corresponding amino acids. WebIn the nucleus, a pre-mRNA is produced through transcription of a region of DNA from a linear chromosome. This transcript must undergo processing (splicing and addition of 5' cap and poly-A tail) while it is still in the nucleus in order to become a mature mRNA. In contrast to introns, exons are the part of an mRNA transcript that actually contain … how to get rid rashes between the legs
