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.

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

The Spindle Assembly Checkpoint

The Spindle Assembly Checkpoint

The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

Assembly of Cytoskeletal Filaments

Assembly of Cytoskeletal Filaments

Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...

Spindle Assembly

Spindle Assembly

Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...

Background:

Advances in DNA sequencing generate vast amounts of genomic data.
Current assembly algorithms struggle to produce complete genomes, yielding fragmented scaffolds.
Existing scaffold assembly methods lack an optimal balance between reliability and cost.

Purpose of the Study:

To develop a new, reliable method for scaffold assembly.
To address limitations in current genomic sequence reconstruction techniques.
To improve the assembly of fragmented genomes using comparative genomics.

Main Methods:

A novel scaffold assembly method analyzing gene orders and genome rearrangements across multiple related genomes.
Application to artificially fragmented mammalian genomes for evaluation.
Testing on highly fragmented Anophelinae genomes and validation against reference-based scaffolding.

Main Results:

The proposed method demonstrates high reliability in assembling artificially fragmented mammalian genomes.
Consistent results were observed when applied to fragmented Anophelinae genomes compared to reference-based scaffolding.
The new method identified a greater number of assembly points than traditional reference-based scaffolding.

Conclusions:

The gene order and genome rearrangement analysis method offers a reliable approach to scaffold assembly.
This method is particularly effective for highly fragmented genomes, improving genomic sequence reconstruction.
The approach provides a valuable alternative or complement to existing scaffolding techniques.
