Which of the following experimental data would suggest the presence of a transmembrane protein? the primary sequence contains stretches of polar and nonpolar amino acids, suggesting an amphipathic design. the protein has windows of the primary sequence with positive hydropathy values separated by windows of the primary sequence with negative hydropathy values. the protein isolates with the membrane fraction of the cell rather than the cytoplasmic fraction of the cell. all of the other answer choices suggest the presence of a multipass transmembrane protein.

All of the other answer choices suggest the presence of a multipass transmembrane protein.

Explanation:

The primary sequence contains stretches of polar and nonpolar amino acids, suggesting an amphipathic design.

This one could be, because of the presence of polar an nonpolar aminoacids. The phospholipids membrane have the same construction.

The protein has windows of the primary sequence with positive hydropathy values separated by windows of the primary sequence with negative hydropathy values.

The same here, having pieces of positive and negative hidropathy can be a sign of transmembrane protein.

The protein isolates with the membrane fraction of the cell rather than the cytoplasmic fraction of the cell.

This is discribing you a transmembrane protein
