DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. DNA replication is the process by which DNA makes a copy of itself during cell division.
A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar, â¦ and a nitrogenous base.These nucleotides connect together to form the double-stranded structure, called the double helix.The double helix structure was founded by Watson & Cricke.n simple terms; the backbone of DNA is made up of a phosphate group and a pentose sugar. The pentose sugar is also known as Deoxyribose and makes up the D in DNA (Deoxyribose â¦ Nucleic Acid). 9 people found this useful.
