Question

In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that __________.a.both lead to integral membrane proteins with the same orientation of C and N termini.b.both are hydrophobic.c.both cause the disassembly or destabilization of the translocon.d.both cause the formation or stabilization of the translocon.

Answer 1

Answer:

In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that both are hydrophobic.

Option: (b)

Explanation:

• Hydrophobic means repelling water.

• Hydrophobic molecules are non polar i.e. that there is no static electric field produce by atoms of molecules.

• Due to this reason the hydrogen cannot form hydrogen bond with the molecules.

• Internal start- transfer process is a transfer process of peptide and moves through the side opening of translocon and the anchor itself in the 'membrane'.

• Stop-transfer sequences in proteins halts the 'process of translocation' and moves out through the 'side opening in translocation' to anchor.
