71.   Through genetic engineering and cloning, for example, animals could be created to produce pharmacological proteins like the clotting factor that hemophiliacs need.

72.   To grow, cells lining the lungs need retinoic acid to produce a protein, retinoic acid receptor-beta.

73.   While genes may help produce the proteins that make the skeleton or the glue, they do not determine the shape and form of an embryo or an organism.

74.   Within three weeks, the cells began producing proteins found only in bone.

75.   Or it may produce a protein that is overly powerful.

76.   A gene called GMF-CSF, which produces a protein that alerts tissues to the presence of foreign substances, was inserted into the cancer cells.

77.   A healthy version of this gene produces a protein that signals cells to grow and multiply normally.

78.   Also, the animal and its descendants must consistently produce protein of the same amount and quality, and the company must prove it can purify the medicine adequately.

79.   But experts praised the research for showing that gene therapy to produce a protein that naturally filters out cholesterol may significantly fight heart disease.

80.   By inserting a human gene into individual tobacco cells, whole tobacco plants can be generated where every cell is capable of producing protein coded for the gene.
