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.

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 …

1 day 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. …

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.

Oct 7, 2024 · The Nobel Prize in Medicine was awarded on Monday to two US scientists for discovering microRNA, a previously unknown type of genetic switch which is hoped can pave …

Oct 11, 2024 · Victor Ambros and Gary Ruvkun were interested in how different cell types develop. They discovered microRNA, a new class of tiny RNA molecules that play a crucial …

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