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 many bases does a single human chromosome contain?
Every chromosome is a different size so the number of base pairs is different for each chromosome. X chromosome has more that 153 million base pairs (greater that 306 million bases) Y chromosome has around 50 million base pairs (around 100 million bases)
How many DNA sequences are in a chromosome?
That depends on the size of the chromosome. We can use the largest and smallest human chromosomes as examples, using size information from the Ensembl genome browser (www.ensembl.org). Human chromosome 1, the largest, is estimated to have 247,249,719 base pairs. That is, the DNA sequence in the chromosome is about 247 million base pairs long. Since DNA is double stranded, that equates to about 494 million nucleotides. The smallest chromosome, 22, on the other hand has 49,691,432 base pairs - about 50 million. Hence it has about 100 million nucleotides.
How many times bigger is the x chromosome from the y chromosome?
In terms of base pairs, the X chromosome is about 155 megabases (million bases), and the Y is about 57 megabases. Note that there can be variation in the lengths of Y chromosomes between men, due to different amounts of constitutive heterochromatin on the long arm. That is, the long arm of the Y contains repeated sequences. The number of these sequences can be different between individuals, thus the size of the chromosome can be different between men.
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
How many base pairs do real human chromosomes consist of?
Approximately ONE-HUNDRED AND FORTY MILLION140,000,000
Is the DNA of the smallest human chromosome nearly 10 times as long as many bacterial chromosomes?
Yes.
What is larger a nucleosome or chromosome?
A chromosome is made up of many genes.
The y chromosome closely resembles many of the other chromosomes. What did you have to do to determine that it was the y chromosome?
The Y chromosome closely resembles many of the other chromosomes. What did you have to do to determine that it was the Y chromosome?
How many chromosomes are in a homologous pair?
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
What kind of tests results are eschechia coli?
Escherichia Coli is called E. coli in its abbreviated version. There are many types of E. coli, most of them are harmless. Some strains of E. coli bacteria can cause severe anemia or kidney failure. Other strains can cause urinary tract infections.
How many cells in 1mg of E. coli cell?
There are 2.547 millions of cells in 1 mg of E coli cells.
How many pages does The Calcutta Chromosome have?
The Calcutta Chromosome by Amitav Ghosh has 288 pages.
