Summary
Comparative genomics reveals evolutionary insights in fish globin genes. This review discusses new methods, including fluorescence in situ hybridization (FISH), and bioinformatic tools for analyzing genome sequences.
Area of Science:
- Genomics
- Evolutionary Biology
- Bioinformatics
Background:
- Genome sequencing presents challenges in biological sciences.
- Comparative genomics aids in functional and evolutionary genome annotation.
- Analysis of genomic sequences offers insights into genome structure and function.
Purpose of the Study:
- To review and discuss new insights into comparative genomics in fish globin genes.
- To highlight the utility of fluorescence in situ hybridization (FISH) as a complementary method.
- To discuss internet resources and bioinformatic tools for sequence analysis.
Main Methods:
- Comparative genomics analysis of fish globin genes.
- Application of fluorescence in situ hybridization (FISH).
- Review of bioinformatic tools and internet resources for sequence alignment and annotation.
Main Results:
- Comparative genomics can identify evolutionary selection pressures (negative or positive) on functional sequences.
- Positively selected regions are crucial for adaptive evolution and biological differences.
- New insights into fish globin gene evolution are discussed.
Conclusions:
- Comparative genomics, particularly in fish globin genes, provides valuable evolutionary and functional information.
- FISH offers a complementary approach to understanding genome organization.
- Advancements in bioinformatic tools enhance the analysis of genomic data.

02:32Osmoregulation in Fishes
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?
01:57Gene Families
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

02:47Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...
02:54Evolutionary 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...
02:37Gene Duplication and Divergence
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.

02:21Globular and Fibrous Proteins
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
