First Passage Time in Computation by Tape-Copying Turing Machines: Slippage of Nascent Tape

  title={First Passage Time in Computation by Tape-Copying Turing Machines: Slippage of Nascent Tape},
  author={Soumendu Ghosh and Shubhadeep Patra and Debashish Chowdhury},
  journal={arXiv: Biological Physics},
Transcription of the genetic message encoded chemically in the sequence of the DNA template is carried out by a molecular machine called RNA polymerase (RNAP). Backward or forward slippage of the nascent RNA with respect to the DNA template strand give rise to a transcript that is, respectively, longer or shorter than the corresponding template. We model a RNAP as a "Tape-copying Turing machine" (TCTM) where the DNA template is the input tape while the nascent RNA strand is the output tape…

RNA polymerases as molecular motors
This chapter discusses the regulation of RNA Polymerase through its Active Center and the mechanics of Transcription Termination.
Nucleic Acids Research
The results suggest that overall polymerase activity fluctuates with a peak occurring at approximately early S phase, which indicates that DNA polymerase I is subject to a complex control and imply that it has a role in both DNA synthesis and DNA repair.
Feynman Lectures on Computation
Although the lectures are over ten years old, most of the material is timeless and presents a "Feynmanesque" overview of many standard and some not-so-standard topics in computer science.
Computation Finite And Infinite Machines
There are very few individuals today who doubt that the computer and its relatives are developing rapidly in capability and complexity, and that these machines are destined to play important (though not as yet fully understood) roles in society's future.
