4. Agroup of scientists isolate a novel strain of bacteria. Although the bacteria have normal nucleic acids and proteins, the strain has an abnormal membrane. In this strain, the lipid bilayer is twice as thick (70 Å) as that of a normal strain of bacteria. This extra thickness is entirely due to longer hydrophobic tails and not due to changes in the charged head groups of the phospholipids that comprise the membrane. If you isolated a single transmembrane helix from a protein from this strain, approximately how many residues would you expect it to have?
