So we have the cell membrane, we have the bacteria phage. So our bottom portion of our tail protein of this bacteriophage attaches itself onto the proper receptor region on that cell membrane. At that point, this capsid essentially injects that nucleic acid into that cell through the midsection and this tail section. So this entire protein tail and caps in the midstation is left behind on the outside of that bacterial cell while this nucleic acid, either DNA or RNA found in the capsid is injected entirely into that bacterial cell. Now in step three we have the assembling process. So now the cell has been infected and the cell is in the latent period.
