Maxam-Gilbert Sequencing01:05

Maxam-Gilbert Sequencing

11.1K
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.

Next-generation Sequencing

87.7K
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.

Sanger Sequencing

753.1K
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...

RNA-seq

9.8K
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...

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...

Genome Annotation and Assembly03:36

Genome Annotation and Assembly

18.8K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Summary

Next-generation sequencing (NGS) data analysis often averages cell populations, but this study shows individual cell dynamics are crucial. A new methodology is proposed to analyze DNA-particle interactions in each cell independently for accurate spatiotemporal kinetics.

Area of Science:

  • Genomics
  • Computational Biology
  • Cellular Dynamics

Background:

  • Next-generation sequencing (NGS) enables genome-wide spatiotemporal analysis.
  • Current methods often interpolate data and assume population homogeneity.
  • This assumption may misrepresent complex cellular dynamics.

Purpose of the Study:

  • To challenge the assumption of population homogeneity in NGS data analysis.
  • To propose a novel methodology for analyzing cellular dynamics.
  • To highlight the importance of individual cell behavior in genomic studies.

Main Methods:

  • Development of a thought experiment termed the "NGS chess problem".
  • Comparison of temporal sequencing data analysis to superimposed chess games.
  • Analysis of spatiotemporal kinetics.

Main Results:

  • Demonstration that population-wide averages can be inappropriate for understanding cellular processes.
  • The "NGS chess problem" illustrates the limitations of current analysis models.
  • Individual cell analysis is critical for accurate interpretation.

Conclusions:

  • A new methodology is advocated for analyzing DNA-particle interactions independently within each cell.
  • This approach is essential even for homogeneous cell populations.
  • Accurate spatiotemporal kinetics require cell-specific analysis.
