Final answer:
RNA interference (RNAi) is used to study gene function by silencing specific genes using small interfering RNAs (siRNAs) or microRNAs (miRNAs). These small RNA molecules bind to mRNA and prevent its translation into proteins, allowing researchers to analyze the effects of gene expression. It can also be used as a therapeutic tool for diseases caused by abnormal gene expression.
Step-by-step explanation:
RNA interference (RNAi) is a process that involves the use of small interfering RNAs (siRNAs) or microRNAs (miRNAs) to interfere with gene expression and study gene function. These small RNA molecules bind to the mRNA transcripts of specific genes and prevent their translation into proteins. By silencing specific genes, researchers can analyze the effects of gene expression on biological processes and identify gene function. RNA interference has also shown promise as a therapeutic tool for diseases caused by abnormal gene expression.
