CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Rather, it is a highly diverse organism with a complex, multi-faceted niche in the wild. Recent studies of ‘wild’ E. coli have, for example, revealed a great deal about its presence in the environment, its diversity and genomic evolution, as well as its role in the human microbiome and disease.

Detailed explanation-2: -An Escherichia coli bacteria (or E. coli bacteria) is typical–it is about one-hundredth the size of a human cell (maybe a micron long and one-tenth of a micron wide), so it is invisible without a microscope.

Detailed explanation-3: -Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal “power plants”, called mitochondria.

Detailed explanation-4: -Yeasts can be readily grown in the laboratory and can be studied by many of the same molecular genetic approaches that have proved so successful with E. coli. Although yeasts do not replicate as rapidly as bacteria, they still divide as frequently as every 2 hours and can easily be grown as colonies from a single cell.
