The lymphatic system includes areas of high concentrations of APCs, T and B cells.
<h3>What is the lymphatic system?</h3>
The lymphatic system is a branch of the circulatory system which consists of a system of organs , tissues, cells and vessels known as lymphatic vessels, which help transport the fluid, lymph around the body.
The lymphatic system contains high concentration of immune cells.
Therefore, the lymphatic system includes areas of high concentrations of APCs, T and B cells.

Answer:
b. Forward or reverse primers
Explanation:
Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.
