Comprehensive Guide to RNA Enzymes: Classification and Mechanisms RNA enzymes are biomacromolecules with catalytic functions, directly involved in or regulating RNA-related biochemical reactions. They are broadly classified into two categories based on molecular composition and activity: I. Ribozymes: Catalytic RNA Molecules Ribozymes are RNA molecules that catalyze specific biochemical reactions through unique three-dimensional structures, challenging the traditional notion that all enzymes are…

RNA Primer: Definition and Functional Insights An RNA primer is a short nucleic acid sequence composed of RNA nucleotides, primarily serving as a starting point for DNA synthesis during DNA replication and reverse transcription. Below is a detailed breakdown of its roles, mechanisms, and applications: 1. Core Functions Provides a 3'-OH Group:DNA polymerases cannot initiate DNA synthesis de novo (without an existing 3'-OH group). RNA primers supply this critical hydroxyl …

In-Depth Analysis of RNA Splicing RNA splicing refers to the process in eukaryotes where precursor mRNA (pre-mRNA) undergoes removal of introns and ligation of exons to form mature mRNA. This process is critical for gene expression regulation, and aberrant splicing can lead to various diseases. Below is a detailed breakdown of its core mechanisms, associated tools, and applications: 1. Biological Mechanisms of RNA Splicing Key Steps: Splice Site Recognition: The spliceosome recognizes conse…

In-Depth Analysis of "RNA Scan" The term "RNA Scan" is not a standardized phrase, and its meaning depends on the specific context. Below are potential interpretations across different fields: 1. Bioinformatics Tools: RNA Sequence/Structure Analysis Definition: Computational tools or workflows for systematically analyzing RNA sequences or structural features. Core Functions: Conserved Element Identification: Align RNA sequences to databases (e.g., Rfam) to discover functional conserved regions (e…

Comprehensive Guide to RNAi Tools: Analysis and Classification RNAi Tools refer to a collection of experimental reagents, bioinformatics software, and database resources designed for the design, analysis, optimization, and application of RNA interference (RNAi) technology. RNAi is a gene-silencing mechanism mediated by double-stranded RNA (dsRNA), enabling specific suppression of target gene expression. This technology holds revolutionary significance in functional genomics, drug developmen…

RNA Enzyme (Ribozyme): Definition and In-Depth Analysis RNA Enzyme (ribozyme) refers to a class of RNA molecules capable of catalyzing specific biochemical reactions independently of proteins. This discovery颠覆ed the traditional enzymology dogma that "all enzymes must be proteins," revealing the multifunctional role of RNA in biological processes. Below is a comprehensive exploration from multiple perspectives. I. Definition and Core Concepts Basic DefinitionRibozymes are catalytic RNA molec…

‌RNA Therapy: A Revolutionary Approach in Biomedicine‌ RNA therapy refers to the use of RNA molecules (e.g., mRNA, siRNA, miRNA, antisense RNA) to directly intervene in disease processes. Recognized for its high efficiency and precision, this approach has emerged as a transformative technology in modern medicine. Below are its core components and classifications. ‌1. Core Types of RNA Therapy‌ ‌(1) mRNA Therapy‌ ‌Principle‌: Synthetic mRNA is delivered into cells to instruct them to produce spec…

‌RNA Primer: Definition and Function‌A ‌RNA primer‌ is a short RNA sequence that provides the 3'-OH terminus required for DNA polymerase to initiate synthesis during DNA replication, PCR amplification, or reverse transcription. Since DNA polymerases cannot synthesize DNA strands de novo (lacking priming ability), RNA primers are essential for replication initiation. ‌DNA Replication‌: In eukaryotes, primase synthesizes RNA primers (~10 nt), which are later extended by DNA pol…

RNA Velocity: Computational Inference of Cellular State Dynamics from Single-Cell Transcriptomics‌ RNA velocity is a computational method that leverages single-cell transcriptomic data to infer the direction and speed of cellular state transitions by analyzing the dynamics of unspliced and spliced mRNA. The core principles are outlined below: ‌Biological Basis‌ mRNA biogenesis involves two key stages: transcription (yielding unspliced pre-mRNA) and splicing (producing mature mRNA). Since unsplic…
