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

Dec 17, 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.

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 …

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 …

Jul 21, 2025 · Within our cells exists a family of tiny molecules called microRNA, which act as regulators of cellular activity. These are not genes that create proteins, but small, non-coding …

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

Jun 3, 2020 · MicroRNAs (miRNAs) are short, regulatory RNAs that act as post-transcriptional repressors of gene expression in diverse biological contexts.

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

4 days ago · MicroRNAs (miRNAs) are short, noncoding RNAs that are key players in regulating genes after they are transcribed, by targeting mRNAs for degradation or inhibiting translation. …

microRNA (miRNA) are small, non-coding RNA molecules that play a crucial role in regulating gene expression by targeting and binding to messenger RNA (mRNA) molecules, leading to …
