Maxam-Gilbert Sequencing

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 Sequencing

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...

DNA as a Genetic Template

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

DNA Topoisomerases

DNA Topoisomerases

Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
Types and Mechanism of action
Topoisomerases are divided into two main types. ...

Summary

This summary is machine-generated.

DNA sequence errors can halt experiments. The Engineered DNA Sequence Syntax Inspector (EDSSI) identifies syntax errors from mutations, misannotations, and unintended open reading frames (ORFs) to improve DNA construct reliability.

Background:

DNA constructs are essential for molecular biology experiments.
Design errors in DNA sequences, termed syntax errors, can lead to experimental failure.
Common causes include point mutations, gene misannotations, and unintended open reading frames (ORFs).

Purpose of the Study:

To develop and validate a bioinformatics tool for detecting DNA syntax errors.
To improve the reliability of DNA constructs used in research.

Main Methods:

The Engineered DNA Sequence Syntax Inspector (EDSSI) pipeline was developed.
EDSSI utilizes GeneMark for ORF prediction, BLAST for sequence homology searches, and the SIFT algorithm for protein sequence error prediction.
An indel addition was incorporated into the SIFT algorithm.

Main Results:

EDSSI successfully identified previously documented DNA syntax errors.
The modified SIFT algorithm demonstrated 97% accuracy in predicting errors in Escherichia coli proteins.
The EDSSI pipeline provides a robust method for identifying potential DNA construct flaws.

Conclusions:

The EDSSI tool effectively detects common DNA syntax errors.
This bioinformatics pipeline enhances the accuracy and success rate of molecular biology experiments by pre-screening DNA sequences.
EDSSI is a valuable resource for researchers working with engineered DNA sequences.
