The majority of chloroplast 1.1x10(6)-mol.wt. rRNA molecules are nicked at specific points in the polynucleotide chain, the molecules being kept intact at low temperatures by their secondary structure. Conditions that break hydrogen bonds and lead to loss of secondary structure cause dissociation of the molecule.
大多数叶绿体1.1×10⁶分子量的核糖体RNA分子在多核苷酸链的特定点被切割,这些分子在低温下因其二级结构而保持完整。破坏氢键并导致二级结构丧失的条件会导致分子解离。
