Now, with DNA origami helicopters, researchers have captured the first recorded rotational steps of a molecular motor as it moved from one DNA
base pair to another.
Base Pair Biotechnologies, Inc reported on Thursday the receipt of a Fast Track Small Business Innovation Research grant from the National Institute on Drug Abuse of the National Institutes of Health to develop new aptamer-based platform to detect opioids and their primary metabolites in newborns.
'All humans have the same genes, in other words, the same basic instructions, but in some people, one DNA
base pair has been changed, ' Schurman said.
That's useful because sometimes just one
base pair in a long strand of DNA gets swapped, deleted, or inserted--a phenomenon called a point mutation.
The DNA was divided into three major parts: G-C
base pair, A-T
base pair, and bridge of
base pairs as it is shown in Figure 2.
These eight groups were 15 motif features (Features 1-15), 10 features corresponding to the sequence (Features 16-25), 17 features corresponding to the sequence (Features 16-32), 9 structural features (Features 33-41), 7 features corresponding to the
base pair (Features 42-48), 22 features corresponding to the motif and
base pair (Features 1-15 and 42-48), 16 features corresponding to structure and
base pair (Features 34-48) and finally, 31 features corresponding to structure,
base pair, and motif (Features 1-15, and 33-48).
Most have focused on individual DNA
base pair changes, often called single nucleotide polymorphisms, or SNPs.
The stability of each
base pair depends upon identity of its nearest neighbor.
Based on previous ab initio calculations, we predicted that (1) Oz forms a stable
base pair with guanine, (2) the Oz:G
base pair is planar, and (3) it has two hydrogen bonds (Figure 1) [8-10].
