DNA comprises the genes and chromosomes that govern the development ... structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A, T, G, and C) on each strand ...

In a groundbreaking study, scientists have discovered a way to manipulate the very fabric of life by using light to reshape DNA strands ... in understanding gene expression and developing ...

Each single strand represents a specific gene sequence. After the cDNA is applied to the microarray chip, the cDNA molecules will bind to any complementary strands that exist on the chip (Figure 3).

coli with two types of viruses that were specifically bred to remove the lactose gene from E. coli. The DNA in these viruses is arranged in two, loosely linked strands, with one molecular strand ...

Between these two strands are nitrogen bases that hold all the genes. Then come the hydrogen bonds, which no longer hold the strands together but still serve the function of making sure the genes ...
