Explain the role of introns in mRNA regulation.
Introns and mRNA regulation:
In biology, an intron is a region or sequence of genetic code, which gets removed during the production of RNA. By contrast, an exon is a sequence that is assembled together in the RNA.
Answer and Explanation:
In regulating (raising or lowering production of) genes, introns determine which parts of mRNA get assembled into the spliced RNA product. Different types of intron perform their own functions. For example, some introns are removed by proteins, while others are removed by RNA catalysis. The introns can regulate genes through the process of RNA assembly. They can also assist in gene regulation in eukaryotes by removing stop codons with bad positions to prevent problems.
