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

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.

Both ends can be simply rejoined with little or no further processing ... can be used to prime DNA synthesis using a homologous region as a template after DNA strand invasion.

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

Fortunately, the models yielded different predictions about the distribution of old versus new DNA in newly divided cells, no matter what ... that consisted of one strand of old DNA bound to ...

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 ...
