Translational control at the level of initiation between mRNAs for pre-existing proteins and a 22-kDa heat-shock protein of Chlamydomonas by small cytosolic RNAs

Small cytosolic RNAs (scRNAs) from human placenta inhibit translation of poly(A)‐rich RNA from Chlamydomonas in the wheat germ cell‐free system. The major exception is the mRNA for a nuclear‐coded 22‐kDa chloroplast heat‐shock protein whose translation is much less affected. Evidence is presented wh...
