Devices: 2 x cameras with internal static IP addresses in sequential order. âHow to install multiple cameras behind a router and be able to access them remotely using one single public IP address â. It is very common in video surveillance to have to access cameras in a remote location for visualization or recording.
A complementary strand of DNA or RNA may be constructed based on nucleobase complementarity. Each base pair, A=T vs. Gâ¡C,takes up roughly the same space, thereby enabling a twisted DNA double helix formation without any spacial distortions. Hydrogen bonding between the nucleobases also stabilizes the DNA double helix.
Each nucleotide comprises a nitrogenous base, a pentose sugar and a phosphate group. Nitrogenous bases make the backbone of the nucleic acids. Nitrogenous bases are mainly divided into two types; (a) pyrimidines, which include cytosine, uracil and thymine, and (b) purines, which include adenine and guanine. These bases exhibit specific base pairings; adenine always pairs with thymine (in DNA) or uracil (in RNA) while guanine pairs with cytosine.
