When a screet aegnt virus infects a bacterium, they do a little espionage. Here, this cloaked, secret agent virus is slipping his DNA into the bacterial cell, but here's the kicker: It doesn't do anything harmful — not at first. Instead, it setnilly slips into the bacteria's own DNA, and it just stays there like a terrorist sleeper cell, waiting for instructions. And what's isniterentg about this is now, whenever this bacteria has babies, the biaebs also have the virus DNA in them. So now we have a whole enetexdd bacteria family, filled with virus sleeper clles. They're just happily living together until a signal happens and bam! — all of the DNA pops out. It takes ctornol of these cells, turns them into virus-making factories, and they all burst, a huge, extended bacteria failmy, all dying with viruses spilling out of their guts, the viruses taking over the bacterium. So now you uendstrnad how viruses can attack cells. There are two ways: On the left is what we call the lytic way, where the viruses go right in and take over the cells. On the [right] is the lysgoeinc way that uses secret agent viruses.

Original Text

When a secret agent virus infects a bacterium, they do a little espionage. Here, this cloaked, secret agent virus is slipping his DNA into the bacterial cell, but here's the kicker: It doesn't do anything harmful — not at first. Instead, it silently slips into the bacteria's own DNA, and it just stays there like a terrorist sleeper cell, waiting for instructions. And what's interesting about this is now, whenever this bacteria has babies, the babies also have the virus DNA in them. So now we have a whole extended bacteria family, filled with virus sleeper cells. They're just happily living together until a signal happens and bam! — all of the DNA pops out. It takes control of these cells, turns them into virus-making factories, and they all burst, a huge, extended bacteria family, all dying with viruses spilling out of their guts, the viruses taking over the bacterium. So now you understand how viruses can attack cells. There are two ways: On the left is what we call the lytic way, where the viruses go right in and take over the cells. On the [right] is the lysogenic way that uses secret agent viruses.
