百度试题 题目简述DNA结构。(DNA’s backbone) 相关知识点: 试题来源: 解析 DNA是以磷酸糖为骨架、由两条反方向平行的剪辑连组成的双螺旋结构。 DNA is a double helix made of two anti-parallel strands of bases on a sugar-phosphate backbone.
What is the composition of the backbone of DNA? DNA: DNA is the hereditary molecule of life. DNA is one of the two classes of nucleic acids the other being RNA. Both DNA and RNA serve a role in gene expression. Answer and Explanation: Become a Study.com member to unlock this answer...
Nano-scale alignment of several proteins with freedom of motion is equivalent to an enormous increase in effective local concentration of proteins and will enable otherwise impossible weak and/or cooperative associations between them or with their ligands. For this purpose, a DNA backbone made of six...
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 l...
DNA is a linear polymer made up of four different types of monomers. The backbone is built of repeating sugar–phosphate units. What base might be attached to each deoxyribose.() A. Adenine B.Cytosine C. Guanine D. Thymine 点击查看答案 ...
DNA backbone conformation in cis–syn pyrimidine[]pyrimidine cyclobutane dimersA theoretical calculation involving minimization of energy functions was made to determine the conformation of a deoxydinucleoside monophosphate pyrimidine[ ]pyrimidine cis-syn cyclobutane dimer. Such single-stranded moieties are ...
Chloride homeostasis is regulated in all cellular compartments. CLC-type channels selectively transport Cl− across biological membranes. It is proposed that side-chains of pore-lining residues determine Cl− selectivity in CLC-type channels, but the
The two U.S. FDA approved oligonucleotide-based drugs on the market both have a modified chemical backbone made of phosphorothioates. The therapeutic advantages of the phosphorothioate group and the new types of gene expression-regulation oligonucleotide
Considering recombination, we describe a consensus phylogeny of the IncP-1 plasmids presenting a divergence into seven distinct clades. We also analysed plasmid DNA signatures and suggest that the IncP-1 plasmids have different host species histories, and that the plasmids have been temporarily ...
Molecular Genetic Manipulations and Design of Constructs—From the sequence of the gene encoding the parent protein, Hsp12.6 (1), the sequence of a novel gene encoding retro-HSP12.6 (RETHSP)1 was created by reversing the sequence of codons used by the parent gene. The DNA encoding the revers...
