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.

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

NMR Spectrometers: Resolution and Error Correction

769
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Genome Copying Errors02:46

Genome Copying Errors

4.4K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their  survival. Therefore, the copying errors are checked and repaired at three levels.

Base Excision Repair01:54

Base Excision Repair

22.9K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • The evolution of DNA sequencing technologies from Sanger to second-generation (2GS) and third-generation (3GS) sequencing has dramatically increased data output.
  • Despite advancements, next-generation sequencing (NGS) data is characterized by a high volume of short reads and inherent error rates.
  • Accurate analysis of massive NGS datasets is crucial for applications ranging from disease detection to crop improvement.

Purpose of the Study:

  • To investigate the performance of k-spectrum-based error correction algorithms for next-generation sequencing (NGS) data.
  • To identify key factors influencing the efficacy of these error correction methods.
  • To provide guidance on selecting appropriate error correction strategies for specific NGS datasets.

Main Methods:

  • Evaluation of various k-spectrum-based error correction algorithms.
  • Analysis of algorithm performance under different data conditions, including coverage depth, read length, and genome size.
  • Comparative assessment of error correction accuracy and efficiency.

Main Results:

  • The performance of k-spectrum-based error correction algorithms is significantly influenced by factors such as coverage depth, read length, and genome size.
  • No single algorithm is universally optimal; performance varies depending on the specific characteristics of the NGS data.
  • Effective error correction is essential for reliable interpretation of NGS data.

Conclusions:

  • Selecting the appropriate error correction method is critical for accurate processing of NGS data.
  • Careful consideration of data characteristics (coverage, read length, genome size) is necessary when choosing an error correction strategy.
