We now know that they have unique physical, chemical, and genetic traits that set them apart from plants and other eukaryotes. For example, the cell walls of fungi are made of chitin, not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food.
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.
Explanation:
An example of homologous structures in vertebrates is
where the wings of bats, front flippers of whales, and forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.
