WebBoth RNA and DNA are large polymers containing repeating structural units, or monomers, called nucleotides. 12.1 Components of Nucleic Acids A nucleotide is composed of three units: an organic base, a sugar, and a phosphate. A) Organic Bases The organic bases found in nucleic acids are derivatives of pyrimidine or purine. WebDouble-stranded DNA has a regular geometric structure with a fixed distance between the two backbones. This requires the bases pairs to consists of one base with a two-ring (bicyclic) structure (these bases are called purines) and one with a single ring structure (these bases are called pyrimidines). cthulhu games online

WebApr 11, 2024 · DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) [GWA-NeeN] or thymine (T). WebNov 10, 2014 · the first step involves the alcohol (or alkoxide) behaving as a nucleophile and attacking the electrophilic carbonyl carbon. At the end of the sequence, when the acetal has been formed, the nucleophilic alcohol has been transformed into an ether, but the nucleophilic center, the "alcoholic" oxygen, remains intact. WebDepending on the actual DNA sequence and the hydration state of the DNA, it can be coaxed to form two other types of double-stranded helices, Z and A DNA. The A form is much more open then the B form. The 3.2 billion base pairs of DNA in humans contains about 24,000 short stretches (genes) that encode different proteins. earth-like planets discovered
