phages can range from 50nm to 200nm.This dimension dont favorizied virused to enty intairlly into their host bacteria.Cell wall of bacteria it is composed of peptidoglycan a glicoprotein that it protect bacteria again enviromental stress and agents.For this reason phages have evolved to inject their genome to the host bacteria.
yes, a bacteriophage is a bacteria/viral particle/any prion/etc... which infects a bacterial cell.
bacteriophage, your welcome everyone cheating on Study Island. C:
mmmm not know me,i dum k
A molecule called tRNA or transfer RNA.
Bacteriophages only infect bacteria, they do not cause disease in humans. The CDC and the WHO classify bacteriophages under biosafety level 1 because they rarely cause human infections. There are only a few exceptions where bacteriophages have causes disease in humans, and that was in a few select people with unique and rare genetic disorders. The only real link between bacteriophages and actual human pathogens, is there ability to alter the genome of non-virulent bacteria strains; thus, producing more virulent strains. One example is Cholera. Most strains of Cholera are harmless, but it has been hypothesized that bacteriophages are partially responsible for 'producing' harmful CHolera strains due to the nature of viral host cell invasion.

The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is the injection of only the viral nucleic acid into the host cell. Viruses that infect bacteria are specifically called bacteriophages.
Protein channels allow the cell membrane to transfer large molecules across it. Remember, diffusion only occurs with small molecules. Protein channels are a necessity to transfer larger molecules.
No. Prokaryotes have no need of protein modification and the ability to ship proteins out of the only cell they are.

No, of course not. Only plants,some bacteria and algae are photosynthetic

Staphlococci are bacteria with a round shape when viewed under a microscope. There are many types of staph bacteria. All bacteria have protein walls which are have a unique molecular structure to the type of bacterium, so only the correct antibody can fit this structure and destroy the bacterium cell.

Bacteriophages are viruses that infect bacteria, and they can only replicate inside a host bacterial cell. While there is debate about whether viruses are classified as living organisms, bacteriophages themselves are considered non-living entities because they cannot reproduce or carry out metabolic processes on their own.
