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.

Study reveals alpha-synuclein's role in enhancing DNA repair in melanoma, linking Parkinson's protein to cancer cell survival ...

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 ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

Using a new method of modeling genetic data, researchers identified a split in human ancestry dating ... But Neanderthal DNA makes up less than 2% of the modern human genome.

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 ...

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 ...
