The function of miRNAs appears to be in gene regulation. For that purpose, a miRNA is complementary to a part of one or more messenger RNAs (mRNAs). Animal miRNAs are usually complementary to a …

Dec 17, 2025 · microRNA (miRNA), small molecule in cells, typically about 21–25 nucleotides in length, that plays a crucial role in the regulation of gene expression. MicroRNA (miRNA) is unique relative to …

MicroRNAs (miRNAs) are a class of non-coding RNAs that play important roles in regulating gene expression. The majority of miRNAs are transcribed from DNA sequences into primary miRNAs and …

Jun 28, 2023 · Here, we summarize the current understanding of miRNA biogenesis, function and regulation, and outline challenges to address in the future.

Jul 19, 2025 · The control of gene expression by microRNAs is part of many physiological processes, ensuring cells develop, function, and are removed correctly. This regulation allows complex …
