What happens to T4 Empty Capsid after Injection ?

What happens to the empty capsid after the phage genome has been injected into the bacteria?

It usually remains on the cell surface until environment favors its dissociation
(activation energy necessary for dissociation of capsids is very high)

oh yeah, hey mr chan! i was just wondering, since viruses are not powered by any neuro system, what exactly propels them to infect innocent bacteria cells? since its genome does not control it's movement- "transduction", what does then? if subjected to "random encounter" theory, then viruses really don't have a high chance of survival right? i mean, randomly moving past millions of bacteria cells, the chances of finding one with matching receptor sites and also contacting at the correct orientation really seems waaaaay low. (:

cheerios,

virus don't care about passing on their genes/survival if we think about them as non-living thing? :) It is like a carefree little vector who is ultra-resilient, dun ya think?

While I suppose the random collision theory sound good but the relative size of the organism should be included as a factor to consider? As you walk across the length of your room, you could be bumping into millions of them, just as a bacteria might meet a lot of them. :)
