22. The discovery of introns provided new insights into the mechanisms of DNA replication and transcription.
23. Some introns are conserved between different species, suggesting they have important functions.
24. Introns can contain regulatory motifs that affect the processing, stability, or translation of mRNA.
25. The presence of introns can influence the timing and regulation of gene expression.
26. The precise mechanisms by which introns are recognized and spliced from RNA are still being investigated.
27. The process of intron removal can result in complex interactions between different RNA molecules.

Common Phases
1.
Introns are non-coding sequences within a gene; they are transcribed into RNA but are later removed by splicing.
2. RNA splicing involves the removal of
introns; the remaining exons are joined together to form a mature mRNA.
3. Many eukaryotic genes contain multiple
introns; this increases the complexity of gene regulation and expression.
4. Alternative splicing can result in different combinations of exons being retained or excluded; this can give rise to multiple protein isoforms from a single gene.
5. Intron retention can also occur in certain circumstances; this can lead to the production of non-functional or aberrant transcripts.
