One key feature of all DNA molecules is their double-helix structure, consisting of two intertwined strands formed by nucleotides. Each nucleotide is made up of a phosphate group, a sugar (deoxyribose), and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The strands are held together by complementary base pairing, where adenine pairs with thymine and cytosine pairs with guanine. This structure enables the storage and transmission of genetic information.
DNA molecules contain genetic information in a double-stranded helical structure, while daughter DNA molecules are formed during DNA replication and consist of two identical copies of the original DNA molecule. Daughter DNA molecules are produced through a semi-conservative process where one strand of the original DNA molecule is conserved in each daughter molecule.
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the complex molecules that contain hereditary information in organisms. They are composed of nucleotide units that carry genetic instructions for the development, functioning, growth, and reproduction of all living organisms.
Replication.
In a double-stranded DNA molecule, adenine (A) pairs with thymine (T). If one strand has 60 adenine molecules, the complementary strand will also have 60 thymine molecules. Therefore, in the double-stranded DNA molecule, there are a total of 60 adenine molecules in one strand and 60 adenine molecules in the complementary strand, resulting in 120 adenine molecules overall.
about one meter for the human genome IIRC.
They are DNA molecules. They are stored in chromosomes
There is no plural of DNA. If you want to be extremely explicit, one might say "DNA molecule" for singular and "DNA molecules" for plural (or something similar), but the letters DNA can refer to one DNA molecule or all DNA molecules on Earth. It really doesn't get confusing - it's like the words fish or moose. Context generally provides enough information for people to figure out whether you're referring to one DNA or a few thousand DNA.

The DNA molecules is one of the molecules that bears and humans have in common, but only 96% of the DNA is common between them.

One important property of DNA that distinguishes it from other molecules is its ability to store and transmit genetic information.
