The zigzag packing that the scientists observed in this study is a kind of nanoscale compromise in which neither relative orientation "wins." Instead, the cubes find the best arrangement to co-exist in an ordered lattice based on whether they have the same or
complementary DNA (i.e., repelling or attracting each other accordingly).
Complementary DNA (cDNA) synthesis:
Complementary DNA synthesis was achieved through two incubation steps.
A large part of these methods is based on hybridization of fluorescent oligonucleotide probe to its
complementary DNA target to generate fluorescent signal.
The RNA was converted to
complementary DNA using a
complementary DNA synthesis kit (Parstous, Tehran, Iran) with both oligo(dT) and random hexamer primers.
Thus
complementary DNA (cDNA), synthesized in the laboratory from the messenger RNA that provides the template for natural DNA, remains patentable.
But the court also ruled that synthetically created DNA known as
complementary DNA (cDNA) can be granted a patent.
But the high court also ruled that synthetically created DNA known as
complementary DNA (cDNA) can be granted a patent.
The Supreme Court of the United States has upheld Myriad Genetics' patent claims on
complementary DNA, or cDNA.
But his ruling said that synthetic molecules known as
complementary DNA can be patented 'because it is not naturally occurring'.
Most of these oligonucleotides also have increased affinity to
complementary DNA. Some analogs such as Peptide Nucleic Acids (PNA) are fairly stable.
