To actually visualize the double-helical structure of DNA, researchers require special ... To see chromosomes in this way, scientists must first use a chemical process that attaches the ...

Small molecules are central players as building blocks, effectors and probes of macromolecular structure and function. The recent explosion of interest in chemical ... of DNA, and later dideoxy ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

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 ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves.

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
