lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

Types of RNA01:20

Types of RNA

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.

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

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-seq03:21

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. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

Summary

This guide explains RNAz, a tool for finding conserved RNA secondary structures. It helps identify potential noncoding RNAs (ncRNAs) by analyzing sequence alignments for stability and conservation.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Many noncoding RNAs (ncRNAs) require specific secondary structures for their biological functions.
  • Identifying functional ncRNAs is crucial for understanding gene regulation and cellular processes.

Purpose of the Study:

  • To provide a comprehensive guide on utilizing the RNAz software for detecting conserved and stable RNA secondary structures.
  • To demonstrate the application of RNAz in identifying candidate ncRNAs within large-scale genomic datasets.

Main Methods:

  • RNAz analyzes multiple sequence alignments to identify regions with conserved and thermodynamically stable RNA secondary structures.
  • The study details basic and advanced usage of RNAz, including a genome-wide screen example.
