Learn what a nucleotide is, what nucleotides are composed of, and the types of nucleotides that exist. Also see the key role of nucleotides in DNA and ATP. Related to this QuestionWhat two molecules make up the sides, or 'backbone,' of the DNA molecule? What forms the backbone of a DN...
A DNA molecule consists of two polynucleotide strands that form a double helix. The strands are held together by hydrogen bonds between the nitrogen-containing bases. One strand is complementary to the other strand, which means that a base on one ...
a(1) Take 2 pieces of electrical wire, each with a different color, and wrap one piece around the other to approximate a double helix. In this construct, each wire represents a sugar-phosphate backbone of a DNA molecule. Connect the light-colored ends and place it flat on the table.The...
DNA is a well-understood molecule made up of pairs of complimentary nucleotide bases that have an affinity for each other. Customized snippets of DNA can cheaply be synthesized by putting the pairs in any order. In their experiments, the researchers took advantage of DNA's natural ability to ...
Based on the example of Cilengitide it is shown that the N-(4-azidobutyl) group exerts similar conformational restraints as a backbone N-Me group and allows conjugation of a desired molecule either via click chemistry or-after azide reduction-via acylation or reductive alkylation.关键词:...

Although there are some exceptions when the side chain is very huge, our work provides a general result for the inherent elasticity of single neutral flexible polymer chains with C-C backbones. 展开 关键词: MOLECULE FORCE SPECTROSCOPY G-ETHYLENE GLYCOL STRANDED-DNA AQUEOUS-SOLUTIONS GRAFT-...
DNAfinite element methodmorse functionAs is known, various important physiological functions and gene engineering processes, such as RNA transcription/DNA replication/DNA repair, involve specific bio-physical mechanics of DNA. Therefore, in this study, a novel single-stranded DNA (ssDNA) model based ...
