Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, RNA or DNA, made up of nucleotides, and membranes, made up of lipids), how they acquire the structures they have, and how alterations in their structures affect their function. Later on, in 1934 the German biologist J. Hammerling, demonstra­ted that the nucleus determines the characters of a cell and ultimately the characters of an individual. In the more derived Chordates, the Vertebrates, the notochord is replaced by the vertebral column, and becomes the cartilaginous substance between vertebrae.The notochord can be seen in the image below, of a lancelet.Lancelets are some of the simplest Chordates. Meaning of Antibody: The term antibody refers to glycoproteins synthesised in response to the administration of an antigen and which react specifically with that antigen and to a variable extent, with molecules of similar structure. It mainly deals with the structural anatomy, physiology, embryology, evolution, classification, habits, growth and differentiation, and distribution of types of cells, including both the dead or living.

The zoological studies deal with the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct. The word zoology is derived from the Ancient Greek word ‘zoon,’ meaning the animal. In the biosphere, over 1 billion tons of chitin are synthesized each year by organisms. Classification of Molecules. The study of animal life is a natural human activity, for man himself can be fully understood only in his setting within the entire range of animal life. Zoology as a branch of life sciences involves work with animals, either in natural surroundings or in captivity. As nouns the difference between zoology and ecology is that zoology is that part of biology which relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct while ecology is the branch of biology dealing with the relationships of organisms with their environment and with each other. | Meaning, pronunciation, translations and examples Zoological definition is - of, relating to, or concerned with zoology.
