Triops is a genus of small crustaceans in the order Notostraca (tadpole shrimp). Some species are considered living fossils, with a fossil record that reaches back to the late Carboniferous, 300 million years ago.
DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.NA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
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. 4 people found this useful.he nucleotides in DNA are made up of three basic components, a sugar, a phosphate and one of four possible bases. The order and sequence of these bases is what encodes geneti â¦ c information.
