The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a cell leading to its division and duplication that produces two daughter cells. In cells without a nucleus‚ the cell cycle occurs via a process termed binary fission. In cells with a nucleus‚ the cell cycle can be divided in three periods: interphase—during which the cell grows‚ accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA—and the mitotic phase‚ during which the

1. BIOLOGICAL CLASSIFICATION Aristotle’s classification - Aristotle was the earliest to attempt a more scientific basis for classification of organisms. - He classified plants into trees‚ shrubs & herbs and animals into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes

The Microbial World The microbial world is a realm of life made up of microorganisms and viruses. Microbiology is the branch of biological sciences concerned with the study of these microbes. Microorganisms are unicellular organisms (capable of existence as single cells)‚ too small to be seen with the naked eye. Among all forms of

The Cell Cycle A eukaryotic cell cannot divide into two‚ the two into four‚ etc. unless two processes alternate: doubling of its genome (DNA) in S phase (synthesis phase) of the cell cycle; halving of that genome during mitosis (M phase). The period between M and S is called G1; that between S and M is G2. So‚ the cell cycle consists of: G1 = growth and preparation of the chromosomes for replication; S = synthesis of DNA [see DNA Replication] and duplication of the centrosome; G2
