Summary
Two-dimensional homochromatography is the most informative method for sequencing oligodeoxyribonucleotides. This technique accurately determines nucleotide sequences up to fifteen bases long, aiding in DNA analysis.
Area of Science:
- Molecular Biology
- Biochemistry
- Genetics
Background:
- Oligodeoxyribonucleotide sequencing is crucial for understanding genetic information.
- Existing electrophoretic and chromatographic systems have limitations for detailed sequence analysis.
Purpose of the Study:
- To compare various electrophoretic and chromatographic systems for oligodeoxyribonucleotide sequence analysis.
- To identify the most effective method for separating sequential degradation products.
Main Methods:
- Investigated and compared several electrophoretic and chromatographic systems.
- Focused on three systems: 2-D electrophoresis, 2-D PEI-cellulose, and 2-D homochromatography.
- Analyzed sequential degradation products of labeled oligonucleotides.
Main Results:
- Two-dimensional homochromatography (System III) was found to be the most informative method.
- System III allows for self-evident identification of omissions in oligonucleotide series.
- Sequenced up to fifteen nucleotides using mobility shifts on the two-dimensional map.
- Successfully sequenced regions of bacteriophage lambda and phi80 DNA.
Conclusions:
- 2-D homochromatography offers superior resolution and information for oligodeoxyribonucleotide sequencing.
- The method enables accurate determination of nucleotide sequences and identification of errors.
- This technique is valuable for analyzing DNA sequences from various sources, including bacteriophages.

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...
Southern Blot
Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.

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

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.

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.
