Summary
DNA barcoding uses a standard DNA marker to identify animal species. This popular method has evolved, showing both strengths and weaknesses in identifying diverse organisms.
Area of Science:
- Zoology
- Genetics
- Bioinformatics
Background:
- The Barcode of Life initiative, launched in 2004, standardized DNA barcoding for species identification.
- DNA barcoding, primarily using cytochrome c oxidase subunit 1, gained traction for cataloging animal life.
Purpose of the Study:
- To outline the principles, advantages, and disadvantages of DNA barcoding.
- To discuss the relevance and universality of the DNA Barcode of Life framework.
- To highlight the evolution and expanded applications of DNA barcoding.
Main Methods:
- Utilized cytochrome c oxidase (COI) gene sequencing for species identification.
- Applied a standardized DNA barcode sequence as a universal marker.
- Reviewed existing research and applications of DNA barcoding across various organisms.
Main Results:
- DNA barcoding has become a popular and evolving technique in zoological research.

03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:57Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
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...
01:05Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
