Unit 15 D1 Prokaryotes Prokaryotes have no organized nucleus but instead they their DNA clumped in an area but there is no organized nucleus with a membrane. This is because prokaryotes don’t have mitosis or meiosis like other cells. Scientists don’t really have a good way of describing how they duplicate‚ but it’s not through normal means. It is sometimes called simple mitosis. On the other hand eukaryotes have a nucleus which contains the DNA and the information necessary to grow reproduce and

ENZYME STRUCTURE AND FUNCTIONS: Enzymes are biological catalysts. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures Definition of enzyme: A protein with catalytic properties due to its power of specific activation is defined as an enzyme. STRUCTURE Enzymes are proteins their function depends on its complexity. The reaction takes place in a small part of the enzyme
