(11) Since these characteristics of the starfish egg poly(A)+ RNA are similar to those of cyclin mRNAs from sea urchin and surf clam eggs, we synthesized a 50-mer antisense-cyclin oligonucleotide probe coding for a part of the sea urchin cyclin cDNA and used this to screen starfish RNA.
(12) They have buckets and trowels as they're going clamming, and Popeye leaves first, navigating the sand with a gratifyingly bandy gait.

(18) Opsonizing and agglutinating activities of plasma from the freshwater clam, Corbicula fluminea, were found to be inhibited by the sugars, 2-deoxy-D-glucose (deoxy-Glu) and N-acetyl-D-galactosamine (GalNAc).
(19) The eggs of the surf clam Spisula solidissima were artificially activated, homogenized at various times in cold 0.5 M MES buffer, 1mM EGTA at pH 6.5, and microtubule polymerization was induced by raising the temperature to 28 degrees C. In homogenates of unactivated eggs few microtubules form and no asters are observed.
(20) Three or four feet down and the sandy sea floor is thickly cast with razor clams and scallop shells.
