Does this experiment show that cd4 is the only membrane protein required for hiv entry? does this experiment show that cd4 is the only membrane protein required for hiv entry? no, the experiment shows that hiv does not utilize cd4 as a receptor. yes, because unbound cells are infected by hiv. yes, because the antibody to a protein other than cd4 was used. no, because the experiment does not test other membrane proteins.

Yes because actually this experiment shows that CD4 was the only membrane protein needed for HIV entry since only CD4 had an antibody added to it and the result leads to no HIV could infect the cell. If other membrane proteins present that were required for HIV entry, then it would also have gotten infected.

yes, because the antibody to a protein other than cd4 was used.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.
