WebGiải thích nghĩa của "Centriole". Each of a pair of minute cylindrical organelles near the nucleus in animal cells, involved in the development of spindle fibres in cell division. Centrosome, Cell, Organelle, Nucleus, Cell membrane, Cytoplasm, Golgi apparatus, Lysosome, Mitochondria, Ribosome, Microsome, Peroxisome. WebThe new centriole forms once in a cell cycle, near each preexisting centriole in a process named ‘centriole duplication’ (Box 1). After centriole duplication, each pair of centrioles (an old and new centriole) is recruited to one of the spindle poles during cell division, such that each daughter cell receives precisely two centrioles.
