While interchromatid unequal BIR could cause rDNA amplification in yeast, a similar intrachro-matid BIR could cause the rolling-circle type amplification of Hot DNA in E. coli. The DRCR model was first proposed by Futcher (1986) for.

•What is the major functional difference of Theta vs. Rolling-Circle replication, specifically in regards to the tandem linear repeats found in the R-C replication. You won’t be responsible for this. Rolling-circle replication may not stop after making one complete genome. This happens in some bacteriophage, in making extrachromosomal DNA replication. Basic Mechanisms of Replication DNA replication is semiconservative. We begin our investigation by describing the basic model for how nucleotides are joined in a specific order during DNA replication. By the early 1950’s, it was clear that DNA was a linear string of deoxyribonucleotides.

Rolling circle replication (RCR), including DNA and RNA replication, is a process found in some bacteriophages or viroids for replicating the DNA or RNA genomes. In vitro versions of this natural phenomenon are the rolling circle amplification (RCA) [ 1 ] and rolling circle transcription (RCT) [ 2 ] that enabled cost-efficient synthesis of concatenated DNA and RNA.
