31.   The beginning and end of each genetic paragraph are concerned with controlling whether the gene makes its protein and how this is done.

32.   The critical gene makes a protein called PrPC.

33.   The fact that one gene can make more than one protein also partly explains the wide variation in estimates of gene numbers.

34.   The gene makes a protein with a deadly role.

35.   The grass genes made him mow?

36.   The gene has made Joe a gentle giant who, along with Jill, was orphaned when young.

37.   The gene normally makes a protein called fibrillin, which forms hairlike structures called microfibrils that give ligaments, tendons, artery walls and other tissues strength and resilience.

38.   The mutant gene makes an abnormal version of a protein called ANK, that transports minerals from the inside of cells to the outside.

39.   The sequence of nucleotides serves as a chemical code, determining which protein the gene makes.

40.   The scientists believe the gene makes a protein that is embedded in the membrane of brain cells.
