RACE - Rapid Amplification of cDNA Ends02:35

RACE - Rapid Amplification of cDNA Ends

Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

Next-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.

RNA-seq03:21

RNA-seq

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 microarray-based...
Maxam-Gilbert Sequencing01:05

Maxam-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.

Sanger Sequencing01:57

Sanger 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...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • High-throughput sequencing advances necessitate accurate genomic sequence reconstruction.
  • Limitations in sequencing require methods to fill unsequenced genomic regions.

Purpose of the Study:

  • To introduce the maxAlike algorithm for reconstructing genomic sequences of a target species.
  • To enhance the accuracy of genomic sequence reconstruction and improve PCR primer design.

Main Methods:

  • The maxAlike algorithm utilizes multiple sequence alignments and phylogenetic trees.
  • It computes nucleotide probabilities for each position in the target species' sequence.
  • Consensus sequences are generated based on a defined confidence level.

Main Results:

  • maxAlike significantly increased reconstruction accuracy in 37 out of 44 species compared to existing methods.
  • Using a confidence threshold, maxAlike improved accuracy by up to 10% across all 44 species.
  • The algorithm reduced primer-template duplex melting temperature prediction errors by ~26%.

Conclusions:

  • maxAlike offers superior genomic sequence reconstruction accuracy.
  • The algorithm enhances the quality of PCR primer design for unsequenced genes.
  • maxAlike demonstrates robustness against phylogenetic tree distortions.
