DNA Isolation

DNA Isolation

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...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

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...

Background:

Existing genome-walking methods often involve complex experimental procedures.
Current techniques can result in short target amplicons and significant background noise.
There is a need for more efficient and practical genome-walking strategies.

Purpose of the Study:

To introduce a simplified and practical fork PCR method for genome walking.
To address the deficiencies of current genome-walking techniques.
To validate the applicability of fork PCR for identifying gene loci.

Main Methods:

Utilized a fork primer set comprising three random oligomers for genome walking.
Employed low-stringency amplification for random primer binding to the genome.
Implemented high-stringency amplification with site-specific primers to selectively amplify target DNA, followed by secondary/tertiary nested PCR for enrichment.

Main Results:

The fork PCR method successfully amplified target DNA while minimizing non-target amplification.
Demonstrated efficient amplification of target single-stranded DNA into double-stranded DNA.
Validated the method's applicability by successfully walking several gene loci.

Conclusions:

Fork PCR offers a simple, practical, and effective approach to genome walking.
The method overcomes limitations such as cumbersome steps and background interference.
Fork PCR presents a promising alternative to existing genome-walking technologies.
