| pubmed-article:3561486 | pubmed:abstractText | The two strands of the DNA molecule are complementary but not identical. Hence, upon semiconservative replication, different parental DNA strands are segregated to daughter cells. A molecular analysis suggests that the process of fission yeast mating-type interconversion uses asymmetry of the DNA strands to generate a regular lineage of cellular differentiation. | lld:pubmed |
