Micro ribonucleic acid (microRNA, miRNA, μRNA) are small, single-stranded, non-coding RNA molecules containing 21–23 nucleotides. [1] .

Nov 22, 2025 · A microRNA (miRNA) is a small molecule in cells, typically about 21–25 nucleotides in length, that plays a crucial role in the regulation of gene expression.

microRNA is the name of a family of molecules that helps cells control the kinds and amounts of proteins they make. That is, cells use microRNA to help control gene expression.

Oct 7, 2024 · Here's what the discovery of microRNA means and how it may affect human health. What is microRNA, anyway? The discovery makes it possible to manipulate which genes are …

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 …

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 · Among these is microRNA (miRNA), a class of small, single-stranded RNA segments about 21 to 23 nucleotides long. Unlike messenger RNA (mRNA), which carries …

MicroRNAs (miRNAs) are a class of small noncoding RNAs, which function in posttranscriptional regulation of gene expression. They are powerful regulators of various cellular activities …

Mature microRNAs regulate gene expression through various mechanisms; partially complementary to mRNA molecules, downregulating gene expression.

Oct 7, 2024 · MicroRNA is one type of these so-called noncoding RNAs. They’re short stretches of genetic material that, rather than coding for a specific protein themselves, control the RNAs …
