DNA Sequencing Techniques

The Shotgun sequencing technique was developed by Craig Venter.
The first organism to have its genome fully sequenced using Shotgun sequencing was Haemophilus influenzae.
The Sanger DNA sequencing method was developed by Frederick Sanger.

Sanger Sequencing

The sequence is determined by analyzing the fragments of different lengths that are generated by the random termination of DNA synthesis.
ddNTPs (dideoxynucleotides) play a crucial role in Sanger sequencing by terminating DNA synthesis, resulting in fragments of different lengths.

Illumina Sequencing

A key feature of Illumina sequencing is its ability to generate millions of sequences in parallel, making it a high-throughput technology.

Genome Sequencing and Annotation

The cost of sequencing a complete genome, including annotation and data analysis, is now relatively low.
The purpose of annotation in DNA sequencing is to identify the functional elements of the genome, such as genes, regulatory elements, and repeats.
Genome sequencing reveals the genetic makeup of an organism, including its genes, regulatory elements, and repeats.

Applications of Genome Sequencing

Genome sequencing provides insights into the biology and evolution of organisms, such as Asgard Archaea.
Genome-wide mutagenesis studies, which involve the systematic disruption of genes in an organism, can be used to identify the function of genes.

Metagenomics and RNA-seq

Metagenomics refers to the study of the collective genomes of microorganisms in a given environment.
The reverse transcription polymerase chain reaction (RT-PCR) method can be used to convert RNA to DNA for sequencing.
Mass spectrometry-based technologies, such as proteomics, can be used to identify proteins and their levels in a sample.
Metagenomics provides information about the diversity, abundance, and function of microorganisms in environmental samples.
RNA-seq provides a complete picture of the transcriptome, which is the set of all RNA transcripts, under a given set of conditions.
