Uranium is a heavy material used to create nuclear energy, when nuclear fission occurs, Uranium releases a lot of energy, that is used to produce thermal energy.
Answer:
The correct answer to the question: What would be the impact of a significant mutation of these phage proteins? Would be, D: The phage may not be able to bind to Salmonella´s surface, blocking viral infection.
Explanation:
Bateriophages are viruses that are capable of infecting bacterial cells and using them as hosts, until they are destroyed. Just like in the human body, however, these phages depend on the presence of certain characteristics in the bacterial cell membrane to be able to infect its host and inject its genetic material. Science has found that bacteriophages use two ways of infecting a bacterial cell; a tail that is able to pierce certain portions of the membrane, but certain conditions must be present on the bacteria for such a thing to be possible, and by using certain proteins on the bacterial wall, to connect to it. Due to evolution, bacteria are highly capable of adapting, and some, especially highly resistant strands, have been seen to form mechanisms to resist against phages. One such changes has been in the availability of membrane proteins, such as OmpF and ToIC, which are vital for phage infection of a bacterial cell. These changes in proteins have reduced the capacity of bacteriophages to infect bacteria, such as in this case, Salmonella enterica.
I think the correct answer from the choices listed above is option A. A potential negative consequence of using genetically engineered medicine would be that g<span>ene markers that are resistant to antibiotics are used, providing the possibility for humans to have increased antibiotic resistance. Hope this answers the question. Have a nice day.</span>
