Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

5.7K
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...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

12.3K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Genomics

36.3K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome-wide Association Studies-GWAS

13.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Comparing Copy Number Variations and SNPs

17.7K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Area of Science:

  • Genomics
  • Bioinformatics
  • Systems Biology

Background:

  • Comparative genomics is crucial for understanding evolutionary relationships and functional divergence between species.
  • Existing tools often lack interactive, high-level graphical overviews of gene function across multiple organisms.

Purpose of the Study:

  • To develop an interactive, web-based software tool, the Comparative Genome Dashboard, for exploring gene function similarities and differences.
  • To provide a graphical survey of cellular functions, enabling detailed examination of biological subsystems.

Main Methods:

  • The Comparative Genome Dashboard presents data in hierarchical panels representing cellular systems (e.g., biosynthesis, metabolism, transport).
  • It utilizes interactive bar graphs to display gene product counts across subsystems for selected organisms.
  • Users can drill down to view compound grids, Gene Ontology (GO) terms, pathway diagrams, and comparative links.

Main Results:

  • The dashboard facilitates high-level graphical surveys of cellular functions and detailed exploration of specific subsystems.
  • It enables users to compare diverse functional capabilities, including cofactor synthesis, metal ion transport, DNA repair, and response proteins.
  • The tool allows for rapid and comprehensive genomic comparisons at multiple levels of detail.

Conclusions:

  • The Comparative Genome Dashboard offers an intuitive platform for comparative genomics research.
  • It enhances the ability to discover functional similarities and differences in gene functions across a wide range of organisms.
  • This tool supports hypothesis generation and detailed analysis in evolutionary and functional genomics studies.
