PERIODIC CHANGES IN THE CONTENT OF PROTEIN-BOUND SULFHYDRYL GROUPS AND TENSION AT THE SURFACE OF STARFISH OOCYTES IN CORRELATION WITH THE MEIOTIC DIVISION CYCLE*
Аннотация:The sulfhydryl content of protein and the tension at the surface were measured for starfish oocytes from the first meiotic division to the cleavage stage. A cyclic change in both the protein-SH and the tension at the surface was found to accompany the division cycle, including the first and second meiotic divisions. It is concluded that the unequal meiotic divisions share the same character with the equal divisions of cleavage, with respect to changes both in the protein-SH and the tension at the surface.
