The circular shape of the E. coli chromosome allows for efficient replication and segregation during cell division. It also provides stability and allows the bacterium to quickly access genetic information when needed. The compact circular structure is beneficial for a single-cell organism like E. coli to efficiently manage its genetic material.

How many base pair long is the E. coli chromosome?

There are several different strains of E. coli, each having about five million (5,000,000) base pairs. For example, uropathogenic E. coli (the one commonly associated with urinary tract infections) has about 5,231,428 base pairs, while E. coli K-12 has 4,639,221. The number of base pairs an organism has in its genes is commonly referred to as genome size. A web search for "genome size E. coli" is how I found these numbers.

How one of the E coli bacteria living in your mouth or intestine is different from one of your own cheek cells lining your mouth?

Cheek cells are eukaryotic, meaning they have a membrane-bound nucleus which contains the cell's DNA. They also have other membrane-bound organelles, like mitochondria. Bacteria, including E. coli, are prokaryotic, meaning they lack a nucleus, and their DNA is contained withing a circular chromosome in the cytoplasm, and they lack other membrane-bound organelles, such as mitochondria.
