What's the difference between mRNA and pre-mRNA ... Furthermore, new exons can be inserted into old introns, creating new proteins without disrupting the function of the old gene.

Exons can be separated by intervening sections of DNA that do not code for proteins, known as introns. Following transcription, new, immature strands of messenger RNA, called pre-mRNA, may contain ...

Heidelberg biochemists and structural biologists from Shanghai unravel the roles of two key regulatory factors in mRNA ...

First, a precursor mRNA (pre-mRNA) is formed that contains both coding information for the protein (exons) as well as non-coding segments (introns). The introns need to be cut out of the pre-mRNA ...

the sequence motifs required are located close by on the pre-mRNA,” said Cooper. “Often, they will be clustered and usually be within the first 100 or 200 nucleotides within the introns. They can also ...

Each tRNA molecule has an anticodon that is complementary to a specific codon on the mRNA. The tRNA binds to its corresponding ... Other ribozymes include self-splicing introns and the RNA component ...

The introns need to be cut out of the pre-mRNA in the cell nucleus and the exons reconnected at the interfaces. This process is known as splicing. Ultimately, the spliced messenger RNA consists of ...
