It involves a painstaking process of extracting and purifying DNA from mosquito samples, followed by sequencing these DNA fragments to determine the order of nucleotides.
This process generates massive amounts of genetic data that must be organized and analyzed to decipher the mosquito’s genetic code.
To begin with, the first step in this process is the selection of mosquitoes with intact and uncontaminated DNA.
These mosquitoes are carefully collected from various regions to capture the genetic diversity within the species.
The DNA is then extracted from the samples using specialized techniques to ensure its purity and integrity.
Once the DNA extraction is complete, the next step is sequencing the mosquito genome. There are different methods available for this, such as Sanger sequencing and Next-Generation Sequencing (NGS).
These techniques enable scientists to read the genetic code of the mosquitoes and generate a vast amount of raw genetic data.
Now comes the challenging part – assembling this enormous amount of data into a meaningful and coherent whole.
Bioinformatics tools and algorithms play a crucial role in this process. These tools help in aligning and merging the overlapping DNA sequences, identifying the genes present in the genome, and determining their functions.
