Crozier (mycology) Crozier (mycology) A crozier is an anatomical feature of many fungi in the phylum Ascomycota that form at the base of asci and look like hook-topped shepherd’s staffs or stylized religious crosiers. During the ascus initial formation the crozier helps to maintain a dikaryotic state in the ascus initial and its side branch that will continue the spreading growth of the ascogenous hyphae in Ascomycota fruitbodies. The tips of developing asci on these ascogenous hyphae curl over. One haploid nucleus migrates into the curved tip while the other compatible haploid nucleus remains in the penultimate space below the hook. The
What Mad Pursuit of the genetic code. There is a prologue outlining Crick's upbringing, education, and war work on magnetic and acoustic mines, and following World War II his decision on what branch of science to study, using the "gossip test". (Your interests are revealed by your gossip.) There is also an epilogue that outlines Crick's work after 1966, his move to the Salk Institute with his career transition to neuroscience concentrating on visual consciousness in primates, and some of his conclusions regarding research in theoretical biology, especially with regard to the brain sciences. Crick comments on various aspects of the DNA double
