Nearly 25 years after scientists completed a draft human genome sequence, many of its 3.1 billion letters remain a puzzle. The 98% of the genome that is not made of protein-coding genes — but which ...
The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...
October 27, 2003--Vast regions of the human genome thought to be genetic "deserts" harboring DNA sequences of no value may actually contain heretofore hidden nuggets of DNA gold. A team of researchers ...
