DNA is named DNA because it is de-oxy ribo nucleic acid. In contrast to RNA, DNA doesnt have 2'-oxygen in the ribose sugar hence it is stable than RNA. Chemically DNA is the same for any genes that code for different proteins.
Phosphorus is essential to living organisms because it forms a part of vital molecules such as DNA and RNA.
Chromosomes are complete molecules of DNA and its attached proteins. A chromosome carries part or all of an organisms genes.

Phosphorus
Those circular DNA molecules are called Plasmids.widely used in Recombinent DNA Technology
DNA Molecules
DNA helicases are proteins, while DNA molecules are nucleotides.
Daughter moloqules are newer than DNA moloqules
Deoxyribose.
DNA replication begins in areas of DNA molecules are called origins of replication.
