Summary
This study developed mathematical models to predict noncoding RNA (ncRNA) secondary structures using minimum free energy (MFE). These models accurately estimate MFE, crucial for understanding ncRNA function and conservation across species.
Area of Science:
- Genomics
- Bioinformatics
- Molecular Biology
Background:
- Noncoding RNA (ncRNA) research is central to genomics.
- ncRNA function is determined by its secondary structure, which is more conserved than its sequence across organisms.
Purpose of the Study:
- To develop mathematical models for predicting ncRNA secondary structures.
- To analyze the relationship between minimum free energy (MFE) and signal properties of ncRNA.
Main Methods:
- Utilized the thermodynamic nearest neighbor model to determine optimal secondary structures (MFE).
- Analyzed MFE for over 2600 ncRNA sequences.
- Developed mathematical models linking MFE to signal properties for four ncRNA classes.
Main Results:
- Established mathematical models correlating MFE with signal properties for different ncRNA classes.
- Achieved high concordance between computed MFE values and those from standard web servers.
- Demonstrated a deviation of MFE values within ±15% for 95% of analyzed sequences compared to standard methods.
Conclusions:
- The developed mathematical models provide accurate predictions of ncRNA secondary structures.
- These models offer a reliable method for estimating MFE, aiding in ncRNA functional and evolutionary studies.

RNA Stability
36.1K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Nucleic Acid Structure
9.9K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.

Ribosomal RNA Synthesis
15.1K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Types of RNA
10.2K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
