Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Sanger Sequencing

756.3K
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 Sequencing

92.3K
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.

Maxam-Gilbert Sequencing

11.4K
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.

MALDI-TOF Mass Spectrometry01:19

MALDI-TOF Mass Spectrometry

5.1K
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.
Matrix-assisted laser desorption ionization (MALDI) is a commonly...

RNA-seq03:21

RNA-seq

10.3K
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...

Area of Science:

  • DNA sequencing is a rapidly advancing field in medical science.
  • It is crucial for detecting genetic mutations linked to diseases.

Background:

  • Traditional DNA sequence comparison methods have high time complexity, O(l*l), due to repetitive character comparisons.
  • Approximate pattern matching is essential as DNA sequences are prone to mutations, necessitating pattern similarity recognition.

Purpose of the Study:

  • To introduce a novel approach, Optimized Pattern Similarity Identification (OPSI), to reduce the time complexity of DNA pattern matching.
  • To improve the efficiency of identifying similar patterns in DNA sequences, even with mismatches.

Main Methods:

  • Developed a methodology called Optimized Pattern Similarity Identification (OPSI).
  • Introduced a supporting table, "Shift Beyond for Avoiding Redundant Comparison" (SBARC), to skip already compared characters.
  • OPSI identifies similar patterns while allowing for a specified number of mismatches (ε).

Main Results:

  • Achieved a reduced time complexity of O(l*ε) for pattern matching.
  • The OPSI algorithm demonstrates scalability, generalizability, and strong performance.
  • OPSI is 69% more efficient than traditional Hamming distance-based approximate pattern matching algorithms.

Conclusions:

  • OPSI offers a significant improvement in the efficiency of DNA sequence analysis.
  • The algorithm's effectiveness in handling mutations and mismatches makes it valuable for various applications.
  • Further discussion covers the algorithm's scalability, generalizability, and overall performance benefits.
