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

the intervening sequences in the DNA strand appear as loops, i.e., the corresponding segments lack counterparts in the RNA. The hybrid could be directly visualized in the electron microscope.

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

For DNA to replicate, the helix must first unwind and break the DNA from a double strand into two single strands. Credit: Taha Shahid et al Upon binding, helicases melt the DNA, breaking the ...

Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a ...

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

Using a new method of modeling genetic data, researchers identified a split in human ancestry dating ... millions of years ago just by looking at DNA today is astonishing,” Aylwyn Scally ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...
