We have isolated and sequenced a set of deletions stimulated by DNA palindromes in Escherichia coli. All of the deletions are asymmetric with respect to the parental sequence and have occurred at short direct repeats. This is consistent with deletion by strand slippage during DNA replication. The orientation of the asymmetry in such deletion products is(More)
Lambda red gam phage carrying a 571 base-pair palindrome are unviable in wild-type Escherichia coli hosts. By using de-methylation to study the fate of DNA strands introduced into E. coli, we have demonstrated that a decrease in the yield of palindrome-containing molecules with two newly synthesized strands can occur without any concomitant loss of(More)
The interaction of three factors determine the detrimental effect of a palindromic DNA sequence in Escherichia coli cells. The first is the nature of the palindrome (its length, extent of central asymmetry and perhaps its base sequence), the second is the genotype of the host cell and the third is the replicon within which it is located. In this paper we(More)
The experimental new media group - Nomads &amp; Homesteaders explore biotechnology, artificial life systems and simulation through, the <i>Open Source Life</i> (OSL) project.OSL participants create artificially intelligent plants, designed to adapt to life in a changing environment. Once created, the virtual plant's survival is the responsibility of its(More)
