During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

The labeled nucleotides were incorporated into growing DNA molecules only during ... The study of DNA replication started almost as soon as the structure of DNA was elucidated, and it continues ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

While scientists have long known the importance of helicase in DNA replication, "they did not know how DNA, helicases and ATP work together in a coordinated cycle to drive DNA unwinding," De ...

This diagram ... the replication of the viral genetic material. Pyrimidine analogs, such as 5-fluorouracil (5-FU) and gemcitabine, are used as chemotherapeutic agents to treat various types of cancer.

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...
