Input-Output Analysis. What is 'Input-Output Analysis'. Input-output analysis (I-O) is a form of economic analysis based on the interdependencies between economic sectors. This method is most commonly used for estimating the impacts of positive or negative economic shocks and analyzing the ripple effects throughout an economy.
The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.
Smaller circular auxiliary DNA strands, called plasmids, are also found in the cytoplasm. Pili-Many species of bacteria have pili (singular, pilus), small hairlike projections emerging from the outside cell surface.ike the chromosome, plasmids are made of a circular piece of DNA. Unlike the chromosome, they are not involved in reproduction. Only the chromosome has the genetic instructions for initiating and carrying out cell division, or binary fission, the primary means of reproduction in bacteria.
