In Biology I learned that a virus head is called a "Capsid." I found this interesting because i didnt know that viruses had heads or even if i did know that they had heads, i wouldn't have known that instead of being called heads, they are called a "Capsid."

yeah i know interesting name i also didnt know that the head is made of protein and is filled with genetic life. very interesting how dna gets involved with bacteria two subjects i didnt even know could have relate
