Study Notes
-
Library preparation involves fragmenting DNA using enzymes or sonication, followed by ligation with custom adaptors.
-
The adaptors contain a sequencer binding site, index, and sequencing primer binding site.
-
Sequencing is performed using clonal amplification methods, such as droplet or bridge PCR.
-
During the sequencing reaction, each nucleotide addition generates an optical or chemical signal.
-
Data analysis involves processing signals to determine the sequence using assembly consensus and determining coverage.
-
Third-generation sequencing (3GS) generates long reads, providing a more complete picture of the genome.
-
3GS technologies include single-molecule real-time sequencing (SMRT) and nanopore sequencing.
-
SMRT sequencing immobilizes a single DNA molecule on a polymerase enzyme and generates long, continuous reads in real-time.
-
Nanopore sequencing threads DNA through a tiny pore and measures changes in electrical conductivity as bases pass through.
-
3GS advantages include generating long reads that span entire genomic regions, resolving ambiguities, and studying complex genomic regions.
-
3GS is used for biomarker discovery, clinical trial design, precision medicine, and bioproduction.
