WebDNA has three constituents: 1) a type of sugar called “ribose”; 2) a phosphate (phosphorous surrounded by oxygen) responsible for its acidity; and 3) four kinds of bases — adenine (A), thymine (T), guanine (G), and cytosine (C). Since these four bases seemed too simple to be able to pass on all the information needed to create a new ... WebDeoxyribose is one of the three components of nucleotides, the building blocks of DNA. Each nucleotide consists of a phosphate group, a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G)—and deoxyribose. DNA's sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring.

WebIf DNA crystals could be flipped upside down and backwards, and still look the same, the strands of the backbone must be identical, and they must run in opposite directions. By this time, Franklin had also concluded that DNA was a two-chain helix, composed of two intertwined sugar-phosphate backbones. WebApr 10, 2024 · A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand … inbde mastery login
