Many G protein-coupled receptors contain seven transmembrane α-helical domains. The amino end of the protein lies at the exterior of the plasma membrane. Loops of amino acids connect the helices either at the exterior surface or on the cytosolic surface of the membrane. The loop on the cytosolic side between helices 5 and 6 is usually substantially longer than the others. Where would a coupled G protein most likely interact with this receptor?

Programmed cell death, or apoptosis, is an
essential part of animal development. In the nematode, with its invariant cell
lineage, particular cell lineages or particular cells within specific lineages
are destined to end in programmed cell death, and it was this feature that
allowed the identification of the process and the analysis of its genetic
control.
Which of the following combination of genes are correct?
