Sanger Sequencing01:57

Sanger Sequencing

755.6K
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...

Next-generation Sequencing03:00

Next-generation Sequencing

92.0K
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.

RNA-seq03:21

RNA-seq

10.2K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

DNA Isolation01:24

DNA Isolation

39.6K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

Evolutionary Relationships through Genome Comparisons

6.1K
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...

Maxam-Gilbert Sequencing01:05

Maxam-Gilbert Sequencing

11.3K
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.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • DNA barcodes are crucial for species identification and require efficient representation for practical applications.
  • Existing methods for DNA barcode representation have limitations in compression efficiency.
  • Standardized DNA sequence data is essential for biological material tracking and recognition.

Purpose of the Study:

  • To develop a novel compression algorithm for DNA barcodes.
  • To create a dynamic DNA QR coding (DDQR) algorithm for efficient DNA barcode representation.
  • To evaluate the performance of DDQR against existing methods and provide a user-friendly web server.

Main Methods:

  • Developed a compression algorithm using binary and Huffman coding, converting binary digits to Base64.
  • Integrated the compression algorithm with QR representation to create the DDQR algorithm.
  • Tested DDQR on simulated and real DNA barcode sequences (rbcL, matK, trnH-psbA, ITS2, COI) and compared it with GeCo3.
  • Upgraded a web server for DNA barcode sequence retrieval, encoding to DDQR, and decoding from DDQR.
