DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene. First established in 1985 by Sir ...

This had helped her deduce that the phosphate part of the molecule was on the ... Watson and Crick showed that each strand of the DNA molecule was a template for the other. During cell division ...

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

An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. mRNA is created during transcription. During the transcription process, a single strand of DNA is ...

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 ...

Then, during the second round of replication, the hybrids would separate, and each strand would pair ... would result in hybrids, or DNA double helices that are part original DNA and part new ...

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 ...
