Rolling circle replication (RCR) is a process of unidirectional nucleic acid replication that can rapidly synthesize multiple copies of circular molecules of DNA or RNA, such as plasmids, the genomes of bacteriophages, and the circular RNA genome of viroids. Some eukaryotic viruses also replicate their DNA or RNA via the rolling circle mechanism.
A concatemer is a long continuous DNA molecule that contains multiple copies of the same DNA sequence linked in series. These polymeric molecules are usually copies of an entire genome linked end to end and separated by cos sites (a protein binding nucleotide sequence that occurs once in each copy of the genome).
Being aware of your cat’s needs and making sure there are plenty of comfortable places for kneading, or “making biscuits,” will help your furry friend remain happy and healthy.
The animal moves up to 2 metres (6.5 ft) at a time by rolling 20–40 times, with speeds of around 72 revolutions per minute. That is 1.5 body lengths per second (3.5 cm/s or 1.4 in/s). Researchers estimate that the stomatopod acts as a true wheel around 40% of the time during this series of rolls.
A plastic tray of mass-produced Fig Newtons Fig Newtons. Fig Newtons are a popular mass-produced cookie similar to a fig roll. In 1892 James Henry Mitchell, a Florida engineer and inventor, received a patent for a machine that could produce a hollow tube of cookie dough and simultaneously fill it with jam. [4]
Direct reciprocity was proposed by Robert Trivers as a mechanism for the evolution of cooperation. [1] If there are repeated encounters between the same two players in an evolutionary game in which each of them can choose either to "cooperate" or "defect", then a strategy of mutual cooperation may be favoured even if it pays each player, in the short term, to defect when the other cooperates.
Rolling chip drop or volume is the amount of rolling chips wagered and dropped at the table (like cash is dropped). Winnings are paid out in cash-equivalent chips. A casino records revenue based ...
A nick is a discontinuity in a double stranded DNA molecule where there is no phosphodiester bond between adjacent nucleotides of one strand.They typically occur through damage or enzyme action.
