metazoa

Examples of metazoa in the following topics:

• Opisthokonts: Animals and Fungi

  • The opisthokonts, or "fungi/metazoa group", are a broad group of eukaryotes, including both the animal and fungus kingdoms, together with the eukaryotic microorganisms that are sometimes grouped in the paraphyletic phylum choanozoa (previously assigned to the protist "kingdom").

• Purine and Pyrimidine Synthesis

  • The first three enzymes of pyrimidine biosynthesis are all coded by the same gene in Metazoa.
  • UDP can also be converted to CTP by CTP synthase cytidine 5'triphosphate (CTP)using glutamine and ATP.The first three enzymes are all coded by the same gene in Metazoa (CAD).

• Phylogeny of the Eukarya

  • The Opisthokonta group includes both animals (Metazoa) and fungi.

• Koch and Pure Culture

  • This is a useful technique for pure culture of fungi, multicellular algae, and small metazoa.

• Constructing an Animal Phylogenetic Tree

  • The current understanding of evolutionary relationships between animal, or Metazoa, phyla begins with the distinction between "true" animals with true differentiated tissues, called Eumetazoa, and animal phyla that do not have true differentiated tissues (such as the sponges), called Parazoa.

• Programmed Cell Death

  • PCD serves fundamental functions during both plant and metazoa (multicellular animal) tissue development.
