Discussion Overview

The discussion centers around the concept of the cell as a biochemical computer, exploring whether biologists recognize this characterization. It involves theoretical considerations of cellular function, comparisons between biological and electronic systems, and implications for understanding cellular processes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that the cell functions as a biochemical computer with molecular memory, processing inputs and producing outputs based on genetic instructions.
  • Others argue that the cell is not only a computer but an intelligent machine, capable of complex functions beyond those of electronic computers.
  • A participant reflects on their changing perspective, suggesting that while they once saw parallels between cells and computers, they now view computers as inadequate models for cellular functions.
  • Another participant agrees that cells are more advanced in their processes compared to electronic computers and acknowledges the question of whether biological processes can perform computations.
  • A mention of a research initiative in Amsterdam aims to create a silicon cell that simulates chemical reactions, though capturing the true nature of living cells is acknowledged as challenging.
  • One participant notes differences between cells and computers, such as flexibility, power requirements, and interdependence.

Areas of Agreement / Disagreement

Participants express a range of views on the comparison between cells and computers, with some agreeing on the advanced nature of cells while others maintain differing perspectives on the validity of the comparison. The discussion remains unresolved regarding the extent to which biologists recognize cells as computers.

Contextual Notes

There are limitations in the discussion, including varying definitions of what constitutes a "computer," the complexity of biological processes, and the challenges in simulating living systems accurately.

Who May Find This Useful

This discussion may be of interest to biologists, computer scientists, and researchers in bioengineering or synthetic biology, as well as those exploring the intersections of biology and technology.

How many biologists recognize that the cell is a biochemical computer with molecular memory? I don't mean it is similar to a computer or analogous to a computer. The cell is one design that might be chosen by someone building a molecular level self replicating computer, particularly for robotic applications.

The cell receives inputs,such as a protein, processes the inputs according to instructions in its memory and then produces a protein output. Biologists often think of the cell's memory, its chromosomes, as consisting of four bases and ignore the special way in which they are arranged. Each two bit "byte" consists of one of two sets of bases and one of the two members of the set will be in the "0 bit" position. This arrangment allows one bit to effectively represent two bits worth of information, a strategy also contemplated for quantum computers.

Recognizing that the cell is a computer would help understand how the cell functions and the role of those sections of DNA sometimes referred to as "junk" DNA. For example, some of this DNA might function as a "data statement" -- an area of information used as values for various instructions.

A cell is not only a computer but an intelligent machine. It's internal programming (a typical human cell only expresses a small portion of its full genome) allows it to carry out specific function that a computer can only "dream" about. Most biologist will not compare a cell do a computer because a cell is way more complicated.
 
This is funny, because I remember back in grade school when I first encountered the functions of the cell. I was like, WOW this is exactly like a computer! And then as I grew older, now in university, I don't think that anymore. If anything, the computer is IMO a crappy model of the cell.
 
I agree with the comments so far, that the cell is a much more advanced computer in its synergy of processes compared to an electronic computer. However, I do understand reasonmclucus question. In slightly different wording, do biologists recognize that biological processes may be used to perform computations? Yes I do.
 
A research group in Amsterdam is trying to build a silicon cell. You input all the chemical reactions, after which you can do simulations with it. Ofcourse it will be hard to capture the true nature of a living cell.

first impression differences, temporarily

cell shape is more flexible, less rigid, can't be taken apart and put back together as easily, most require constant power to survive, sometimes need computers help to survive although computers need cells help to survive.
Interesting thoughts.
