There are three amino acids that have basic side chains at neutral pH. These are arginine, lysine, and histidine. Their side chains contain nitrogen and resemble ammonia, which is a base.
Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process.So, arginine is basic amino acid.
