Synthetic conformation of DNA. C-DNA, also known as C-form DNA, is one of many possible double helical conformations of DNA. DNA can be induced to take this form in particular conditions such as relatively low humidity and the presence of certain ions, such as Li + or Mg 2+, but C-form DNA is not very stable and does not occur naturally in living organisms. The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the 'Grand Old Ditch,' operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
C-Murder's financial woes reportedly landed him the help of two Harvard attorneys, one of them Ronald Sullivan, who have agreed to assist with his appeal. One of the jurors, Mary Jacob, said that both she and a fellow juror, a 20-year-old student at Xavier University of Louisiana, were verbally abused by fellow jurors for their decision to acquit. Lockheed C-5 Galaxy loading on a wet ramp in Bush Field, Georgia. The C-5 is a large, high-wing cargo aircraft with a distinctive high T-tailfin (vertical) stabilizer, with four TF39turbofanengines mounted on pylonsbeneath wings that are swept25°. (The C-5M uses newer GE CF6 engines.). In the C programming language, operations can be performed on a bit level using bitwise operators. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR and NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits at a time. The reason for this is that a byte is normally the smallest unit of addressable memory. This applies to bitwise operators as well, which mea.

Recent research suggests that both C-DNA and B-DNA consist of two distinct nucleotide conformations, B-I and B-II. The ratio of B-II conformation in C-DNA is more than 40%, but in B-DNA the ratio is only about 10%. C-DNA exists as a double helix with a right-handed turn and 9.33 base pairs per full turn.
Counterions such as primary amides under basic conditions have been used in experiments to show the relationship between B and C forms of DNA.[1] The overall shape and orientation of DNA is heavily dependent on its primary sequence as well as hydrogen bonding between its base pairs, which stabilizes and maintains the double helix conformation. C-DNA was shown to hold its conformation in the absence of water and was able to form upon dehydration.[1] Some amides under basic conditions and low humidity were shown to hold the C-form conformation, but smoothly transitioned to B-form DNA as the humidity was increased.[1] This may suggest a strong correlation between C-form and B-form DNA, which was also seen using lithium salt at low humidity.[2][3][4][5]
