SIRNAS Meaning and
Definition
-
SIRNAs, which stands for Short Interfering RNAs, are a class of small RNA molecules that play a crucial role in gene regulation and control. They are involved in a process known as RNA interference (RNAi), which is a natural cellular mechanism that helps regulate gene expression.
The main function of SIRNAs is to target and silence specific genes by binding to their respective messenger RNA (mRNA) molecules. This binding disrupts the protein synthesis process and prevents the target gene from being translated into its corresponding protein product. As a result, the expression of the target gene is post-transcriptionally suppressed.
SIRNAs are typically 20-25 nucleotides long and are produced within cells or introduced from external sources. They are guided to their target mRNA through a complementary base pairing mechanism, where the SIRNA's sequence matches that of the target mRNA. This specific binding triggers a set of enzymatic reactions that lead to mRNA degradation or inhibition, effectively silencing the target gene.
Research on SIRNAs has significantly contributed to our understanding of gene regulation and has paved the way for the development of therapeutic applications. SIRNAs have been extensively studied for their potential as therapeutic agents for various diseases, including cancer, viral infections, and genetic disorders. Their ability to selectively silence specific genes makes them a promising tool for manipulating gene expression and has opened up new avenues for targeted therapies.
