Combinations of these atoms form the sugar-phosphate backbone of the DNA ... special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in ...

This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain ...

internally crosslinked by the covalent backbone of a single DNA molecule. The spontaneous formation of well-defined three-dimensional patterns is in agreement with contemporary research in ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

This keeps the DNA molecule in the form of a ribbon of consistent ... the sugar-phosphate backbone is the fabric to which the teeth are attached. Because of the shape of the nucleobases—and ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...

The Stratos team designed a molecule that is copied from DNA ... to the base by a nitrogen that is not part of the backbone of natural DNA, and each monomer also includes a large hairpin-shaped ...

DNA (deoxyribonucleic acid ... steps to test for matches with its guide RNA molecule. Artificial nucleic acids with a fixed conformation of the backbone of the oligonucleotide can form stable ...
