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.

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 …

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.

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 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 …

Jan 21, 2025 · Discovered in the early 1990s, miRNAs have since emerged as key players in a wide range of biological processes, including development, differentiation, and cellular …

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

A microRNA is a single-stranded RNA of short length (18–25 nucleotides) whose function is not to encode proteins, but to regulate other biological processes such as cell proliferation or …
