|November 1, 1979
Abstract:
Procollagen 27S mRNA was isolated from heavy polysomes of human embryo fibroblasts. This RNA directed the synthesis of collagenase sensitive polypeptides in wheat germ translation system and was active in reverse transcription.
Insights
Researchers isolated Procollagen 27S messenger RNA (mRNA) from human cells. This mRNA successfully directed the synthesis of collagenase-sensitive proteins in a cell-free system, indicating its functional capacity.
Area of Science:
