What does DNA sequencing of a complete genome consist of?

DNA sequencing is a technology that allows us to know and decipher the genetic information of a living being. In other words, sequencing a genome consists of ‘reading’ that genome, which contains essential information for its development and functioning, as if it were a genetic handbook.

The most relevant detail of sequencing is that it obtains the exact order of the nucleotides in an organism’s genome. The entire genome undergoes the same process, thereby analyzing all of the individual’s genes in full. This is how it differs from other methods that only work with a part of the individual’s DNA, which in turn speeds up costs and times.

Therefore, sequencing should not be confused with other processes such as genotyping.
