Information processing, an analogy between biology and computer science.[1] | |
Biology | Computer science |
1. Digital alphabet consists of bases A, C, T, G | 1. Digital alphabet consists of 0, 1 |
2. Codons consist of three bases | 2. Computer bits form bytes |
3. Genes consist of codons | 3. Files consist of bytes |
4. Promoters indicate gene locations | 4. File-allocation table indicates file locations |
5. DNA information is transcribed into hnRNA and processed into mRNA | 5. Disc information is transcribed into RAM |
6. mRNA information is translated into proteins | 6. RAM information is translated onto a screen or paper |
7. Genes may be organized into operons or groups with similar promoters | 7. Files are organized into folders |
8. "Old" genes are not destroyed; their promoters become nonfunctional | 8. "Old" files are not destroyed; references to their location are deleted |
9. Entire chromosomes are replicated | 9. Entire discs can be copied |
10. Genes can diversify into a family of genes through duplication | 10. Files can be modified into a family of related files |
11. DNA from a donor can be inserted into host chromosomes | 11. Digital information can be inserted into files |
12. Biological viruses disrupt genetic instructions | 12. Computer viruses disrupt software instructions |
13. Natural selection modifies the genetic basis of organism design | 13. Natural selection procedures modify the software that specifies a machine design |
14. A successful genotype in a natural population outcompetes others | 14. A successful website attracts more "hits" than others |
