Nucleotides. A single nucleotide contains a phosphate group, deoxyribose or ribose (depending on the nucleic acid) and a nitrogen base, which can be adenine, guanine, cytosine â¦ , thymine, and uracil. These monomers combine to form polymers known as DNA or RNA.
On the average, a single human chromosome consists of DNA molecule that is about 2 inches long.. 2.3 m. The chromosomes in the nucleus of a cell contain all the information a cell needs to carry on its life processes. They are made up of a complex chemical (a nucleic acid) called deoxyribonucleic acid, or DNA for short. Scientist's decoding of the chemical structure of DNA has led to a simple conceptual understanding of genetic processes. DNA is the hereditary material of all cells.
