Markov Process. A Markov process is a process that is capable of being in more than one state, can make transitions among those states, and in which the states available and transition probabilities depend only upon what state the system is currently in. In other words, there is no memory in a Markov process.
Complementarity between two antiparallel strands of DNA. The top strand goes from the left to the right and the lower strand goes from the right to the left lining them up. Left: the nucleotide base pairs that can form in double-stranded DNA. Between A and T there are two hydrogen bonds, while there are three between C and G. Right: two complementary strands of DNA.
If the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.n the complementary side of the DNA molecule, the primer would have a phosphate not a sugar at its exposed end; new nucleotides can only join to a sugar end. To get around this problem, this strand is synthesized in small pieces backward from the overall direction of replication.
