In the DNA molecule

A segment of DNA molecule contains 20,000 base pairs. What is the number of phosphate molecule in this DNA molecule ?

In the eukaryotes the DNA molecules are organised within the nucleus. How is the DNA molecule organised in a bacterial cell in absence of a nucleus

A double stranded DNA molecule has 20% of cytosine. Using Chargaff's law calculate the percentage of adenine in this DNA molecule?

In the eukaryotes the DNA molecules are organised within the nucleus. How is the DNA molecule organised in a bacterial cell in absence of a nucleus?

If the base sequence along one side af a DNA molecule is TTCGA, then the complementary sequence of bases on the other side of the DNA molecule is :
