DNA Isolation01:24

DNA Isolation

45.3K
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...

Sanger Sequencing

775.3K
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

98.9K
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.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Gene Conversion

10.7K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Conservative Site-specific Recombination and Phase Variation

6.9K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Area of Science:

  • Molecular Biology
  • Genomics
  • Biotechnology

Background:

  • Introns and non-coding regions complicate direct gene analysis from genomic DNA.
  • Traditional methods for obtaining coding sequences require RNA extraction and cDNA synthesis, which are not always feasible.

Purpose of the Study:

  • To present a novel, rapid, and cost-effective in vitro technique for generating continuous coding DNA sequences.
  • To demonstrate the utility of this method when tissue samples for RNA extraction are unavailable.

Main Methods:

  • The study introduces SPLICE (swift PCR for ligating in vitro constructed exons), an overlapping fusion-PCR strategy.
  • This method removes introns and other unwanted regions directly from genomic DNA.

Main Results:

  • SPLICE successfully generated a continuous coding sequence for the Eulemur fulvus SWS1 opsin gene in two PCR rounds.
  • The technique efficiently produced a single DNA fragment containing the complete coding region.

Conclusions:

  • SPLICE offers a universally applicable method for creating practical DNA units for gene function studies.
  • This technique is valuable when genomic structure is known and traditional RNA-based methods are not viable.
