Structure of DNA: Practice Dna Structure And Replication Answer Key
DNA is a double helix molecule that contains the instructions for an organism’s development and characteristics. It is made up of two strands of nucleotides, which are linked together by hydrogen bonds. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base.
The four different nitrogenous bases are adenine (A), thymine (T), cytosine (C), and guanine (G). A always pairs with T, and C always pairs with G. This pairing is known as complementary base pairing.The double helix structure of DNA was first discovered by James Watson and Francis Crick in 1953. Their model showed that the two strands of DNA are twisted around each other in a spiral shape.
The sugar-phosphate backbones of the two strands run along the outside of the helix, while the nitrogenous bases are stacked inside. The double helix structure of DNA is essential for its function, as it allows the DNA to be copied accurately during cell division.
Components of DNA, Practice Dna Structure And Replication Answer Key
DNA is composed of three main components: deoxyribose sugar, phosphate groups, and nitrogenous bases. Deoxyribose sugar is a five-carbon sugar that forms the backbone of the DNA molecule. Phosphate groups are negatively charged molecules that link the deoxyribose sugars together.
Nitrogenous bases are organic molecules that contain nitrogen and are attached to the deoxyribose sugars. The four different nitrogenous bases are adenine (A), thymine (T), cytosine (C), and guanine (G).
