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 ...

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 ...

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

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

Later, in 1960, the discovery that an RNA molecule and a DNA molecule could form a hybrid ... these RNAs all share the same basic single-stranded chemical structure with, in some cases, higher ...

By unveiling Pol-theta's DNA-bound structure—its active state—the ... Pol-theta is an enzyme—a type of protein that speeds up ...

Chemical structure of guanine, showing its double-ring purine structure ... This strong base pairing is crucial for the stability of the DNA double helix and the accurate replication and transcription ...

Get Instant Summarized Text (Gist) The DNA repair protein RAD52 has been found to adopt a unique double-ring structure when binding to DNA, which may aid in developing new cancer treatments. This ...

Deoxyribonucleic acid (DNA) is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like ...

Uracil is often compared to thymine (T), which is the nucleobase that takes its place in DNA. Both uracil and thymine pair with adenine, but they differ in their chemical structure. Thymine has an ...

Get Instant Summarized Text (Gist) Scientists have directly observed the initial steps of DNA unwinding, a crucial process for DNA replication. Using cryo-electron microscopy and deep learning ...

Several current areas of interest are motor-protein motion and collective effects in motor-filament interactions, the biophysics of cell division, DNA elasticity ... revolves around the chemical ...
