Document Summary
If the(cid:396)es lots of phages a(cid:396)ou(cid:374)d, (cid:449)e do(cid:374)"t (cid:374)eed to make more of them. All of these events occur within the first few minutes of the phage dna being injected. Once the decision is made between the 2, it cant go back. This is just one system, theres numerous systems. Phages infecting one cell can send signals to other cells being infected by phages, they can communicate with eachother in different cells. Dna damage is a signal for the phages to leave the cell as it is dying. The phages make particles and remove their genome from the host genome and leave the cell. Theres a variety of mechanisms that the (cid:272)ell (cid:272)a(cid:374) do this th(cid:396)ough. The p(cid:396)otei(cid:374) that"s key i(cid:374) this (cid:373)e(cid:272)ha(cid:374)is(cid:373) is the re(cid:272)a p(cid:396)otei(cid:374) that"s a (cid:272)o(cid:374)se(cid:396)(cid:448)ed p(cid:396)otei(cid:374) i(cid:374) (cid:373)ost (cid:271)a(cid:272)te(cid:396)ia, it"s a si(cid:374)gle st(cid:396)a(cid:374)ded d(cid:374)a binding protein, and when it binds to dna it helps the repair process.
