What is the structure of DNA bases? DNA is a long chain of smaller subunits called nucleotides. Each nucleotide has one nitrogenous base, a deoxyribose sugar, and a phosphate group. The outside (backbone) of DNA is composed of alternating sugars and phosphates, while the inside is the base...
In DNA structure, which bases pair with each other? A. Adenine and guanine B. Cytosin
Which feature of the DNA and RNA structure enables them to act as informational molecules? What does DNA stand for and what are the four bases of DNA? How the structure of DNA contributes to a cell's ability to replicate it? What is the threadlike structure made up of nucleotides and...
Although nucleotides derive their names from the nitrogenous bases they contain, they owe much of their structure and bonding capabilities to their deoxyribose molecule. The central portion of this molecule contains five carbon atoms arranged in the shape of a ring, and each carbon in the ring is...
structure resembling a ladder twisted into a spiral, called adouble helix.Each rung is made up of two chemical bases, callednucleotides,that are joined together by hydrogen bonds. There are four kinds of nucleotides in a DNA molecule: cytosine, guanine, adenine, and thymine—C, G, A, and ...
Answer and Explanation:1 The 3-dimensional structure of DNA is called adouble helixbecause each DNA molecule consists of two chains of nucleotides that are paired along... Learn more about this topic: DNA | Definition, Characteristics & Sequencing ...

The influence of molecular structure and DNA binding mode on the ability of cationic porphyrins to photosensitize DNA strand break formation has been studied for a series of meso-substituted pyridinium porphyrins using electrophoretic and DNA sequencing techniques. Porphyrins substituted with pyridyl groups...

The bases on each strand are joined to the bases on the other strand with hydrogen bonds, but different bases have different chemical structures. Cytosine and thymine (and uracil in RNA) are pyrimidines, containing one ring. Adenine and guanine are purines, containing two rings. The pyrimidine...
