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.
Answer: Based on fact, Free from bias, objective
Explanation:
Answer: The answer is A, Transcription
Answer:
The correct answer is nucleus
Explanation:
DNA is made up of nucleotides, a deoxyribose sugar, and a phosphate group. There are four types of nucleotides which make the DNA that are adenine, guanine, cytosine, and thymine. DNA is formed inside the nucleus and after transcription, it forms RNA that moves out of the nucleus through the nuclear pore.
So if a plant cell containing radioactive nucleotides is grown in a test tube than after examination of cell the radioactivity will be concentrated in the nucleus because DNA is formed in the nucleus and nucleotide are its constituent.
It can not make the combination of TT
