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.
DNA and RNA Bases. In DNA, there are four different bases: adenine (A) and guanine (G) are the larger purines. Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).
