Nucleotides
Genes are relatively small sections of DNA which encode (provide a template for) proteins. Chromosomes are molecules that consist of very long strand of DNA coiled many times, & a few proteins called histones which hold the whole structure together.
In the conservative model of DNA replication, the parental DNA molecule remains intact and serves as a template for the synthesis of a completely new daughter DNA molecule. The resulting progeny DNA molecules, therefore, consist of one entirely old parental strand and one entirely new daughter strand.
DNA molecules consist of a sugar (deoxyribose), a phosphate and a nitrogenous base. Together, these three components are called a nucleotide.
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.
no but has many small molecules
This is the deoxyribonucleic acid (DNA).
This is the deoxyribonucleic acid (DNA).

The molecules of DNA are referred to as nucleotides, which are the building blocks of DNA. Nucleotides consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). Multiple nucleotides are strung together to form the double helix structure of DNA.
Nucleotides are the building blocks of important life-sustaining molecules such as DNA and RNA. These molecules consist of a sugar, a phosphate group, and a nitrogenous base, which combine to form the genetic information necessary for cell function and replication.
The sides of the DNA latter consist of the sugar deoxyribose and phosphates. The bond between the latter and the nitrogen bases together is known a a nucleotide. Nucleotides are molecules that make up the structure of DNA and RNA.
Each DNA molecule includes units of inherited information called genes. DNA is desoxyribose nucleic acid. DNA carries the genetic code that determines the characteristics of a living thing. Genes are related to DNA because they are short sections of DNA that code for specific proteins.
