For example, the HNH domain was fused to the C-terminus of Cas5, replacing the need for Cas3, a protein commonly involved in DNA degradation in other systems. This structural innovation pointed to ...

With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.

If DNA is a book, then how is it read ... Another cofactor, TFIIB, recognizes a different common consensus sequence, G/C G/C G/C G C C C, approximately 38 to 32 bases upstream (Figure 4).

and C and G nucleotides always pair with one another. This phenomenon is known as complementary base pairing (Figure 4), and it results in the production of two complementary strands of DNA.

The small study in patients with a rare disorder that causes liver and lung damage showed the potential for precisely targeted infusions. By Gina Kolata Researchers have corrected a disease ...
