DNA is a long polymer, made from repeating units called nucleotides. DNA is found in mitochondria, plastid & nucleolus. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase either guanine (G), adenine (A), thymine (T), or cytosine (C) as well as a monosaccharide sugar called deoxyribose and a phosphate group. The presence of deoxyribose sugar is characteristic of DNA.
things that we do daily such as driving for example, has an effect on our ecosystem. Driving pollutes the air in our ecosystem and uses up gas and diesel resources.
Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.
It could perhaps provide a better understanding of why dinosaurs went extinct. It could also provide some of the things Dino's ate and their average life style.
