Lambda phage consists of a virus particle including a head (also known as a capsid), a tail, and tail fibers. The head contains the phage's double-stranded circular DNA genome. The phage particle recognizes and binds to its host, E. coli, causing DNA in the head of the phage to be ejected through the tail into the cytoplasm of the bacterial cell. Lambda phage DNA is commonly used as a DNA molecular weight marker. Digestion of the Lambda phage genome with HindIII produces a set of 8 fragments consisting of 125, 560, 2000, 2300, 4300, 9400, and 23000 base pairs.
