1. Introduction-celldivision
Celldivision is the process by which a parent cell divides into two or more daughter cells. Cell arise only from preexisting cells. Celldivision plays several important roles in the live of organism. Celldivision on large scale allows some multicellular organism reproduce asexually (such as plants that grow from cuttings.) Among sexually reproducing organisms
2. Types of celldivision
Prokaryotes reproduce by a type of celldivision ccalled binary fission. In typical prokaryotes, most genes are carried on a circular DNA molecule that, associated protein, constitutes the organism's single chromosome. Although prokayotic chromosomes are much smaller than those of eukaryotes, duplicating them in an orderly fashion and distributing the copies equally to
The potential difference above the equilibrium value required to produce a current which depends on the activation energy of the redox event.

1. 염색체 (chromosome)
생물 세포의 핵 속에 있는 DNA를 주성분으로 하는 자기증식성의 소체(小體). 헤마톡실린이나 카민 등의 염기성색소에 염색이
Ⅰ. 서 론
미생물이란 육안의 가시한계를 넘어선 0.1 mm 이하의 크기인 미세한 생물로서 주로 단일세포 또는 균사로써 몸을 이루며, 생물로서 최소 생활단위를 영위한다. 조류(algae), 균류(bacteria), 원생동물류(protozoa), 사상균류(mold), 효모류(yeast)와 한계적 생물이라고 할 수 있는 바이러스(virus) 등이 이에
