Deep sequencing refers to sequencing a genomic region multiple times, sometimes hundreds or even thousands of times.
Deep sequencing refers to the general concept of aiming for high number of unique reads of each region of a sequence
Its a high-throughput sequencing method that is based on new and powerful technologies, which allow sequencing billions of nucleotide in a single run.
This next-generation sequencing (NGS) approach allows researchers to detect rare clonal types, cells, or microbes comprising as little as 1% of the original sample.
