Summary
EVidenceModeler (EVM) is an automated tool for eukaryotic gene annotation. It predicts protein-coding genes and isoforms with accuracy comparable to manual curation when used with the Program to Assemble Spliced Alignments (PASA).
Area of Science:
- Genomics
- Bioinformatics
- Computational Biology
Background:
- Accurate eukaryotic gene structure annotation is crucial for understanding genome function.
- Existing annotation methods can be labor-intensive and may lack comprehensive integration of diverse evidence types.
Purpose of the Study:
- To present EVidenceModeler (EVM) as an automated tool for eukaryotic gene structure annotation.
- To demonstrate the capability of EVM, when combined with the Program to Assemble Spliced Alignments (PASA), to predict protein-coding genes and alternatively spliced isoforms.
Main Methods:
- EVM integrates and weights various evidence sources to predict gene structures.
- The system utilizes the Program to Assemble Spliced Alignments (PASA) for comprehensive analysis.
- Experiments were conducted on rice and human genome sequences.
Main Results:
- EVM provides automated gene structure annotation based on a weighted consensus of evidence.
- The combined EVM-PASA system generates a configurable annotation pipeline.
- Automated annotation quality achieved by EVM approaches that of manual curation.
Conclusions:
- EVidenceModeler (EVM) offers an effective automated solution for eukaryotic gene annotation.
- The integration of EVM with PASA provides a powerful system for predicting protein-coding genes and isoforms.
- The tool demonstrates high accuracy, rivaling manual annotation efforts.

03:36Genome Annotation and Assembly
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
01:28Prokaryotic Gene Structure and Organization
Prokaryotic genomes exhibit a streamlined organization of coding and non-coding regions essential for gene expression and protein synthesis. While coding regions contain the genetic instructions for proteins or functional RNAs, non-coding regions regulate the precise transcription and translation of these genes.Coding Regions: Proteins and RNAsThe primary coding regions, known as structural genes, include sequences transcribed into messenger RNA (mRNA) and ultimately translated into...
00:58Genomic DNA in Eukaryotes
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.
02:41Protein Complex Assembly
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

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.
