of
Lambda λ -
The lambda phage particles are half protein and, half DNA. The head is icosahedral in shape, and about 55 um in diameter.
The capsid consists of between 300 and 600 subunits of molecular weight 37,500.
The subunits appear to be arranged in clusters ,of 5 and 6 subunits, the pentons and the hexons: respectively. The head appears to consist of more than one type of subunit.
It is joined to the tail by, ahead tail connector. This consists of a 'narrow' (led, portion which passes through 11 hole in the capsid, and expands into a knob inside.
