Genome Annotation and Assembly

Genome 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.

Area of Science:

Bioinformatics
Computational Biology
Genomics

Background:

Sequence analysis tools often face computational limitations with large datasets.
Existing graphical interfaces may lack efficiency for complex genomic data.

Purpose of the Study:

To develop an interactive software tool for nucleotide and protein sequence analysis.
To overcome computational limitations of existing tools for large sequence datasets.

Main Methods:

Developed SeqEditor, a cross-platform desktop application with a Graphical User Interface.
Optimized for managing large sequences (contigs, scaffolds, chromosomes) and annotation files (GTF/GFF).
Incorporated tools for singleplex and multiplex PCR primer design and pooling.

Main Results:

SeqEditor efficiently manages large sequences and annotation files, comparable to command-line tools.
Provides a GTF/GFF viewer for managing annotation data.
Offers optimized primer design tools for specific PCR assays.

Conclusions:

SeqEditor is a flexible application for complex sequence analysis, primer design, and dataset management.
Enhances efficiency in analyzing reference genomes and transcriptomes.
Facilitates PCR assay development for diagnostic applications.
