Asymmetric gene conversion at inserted segments on yeast mitochondrial DNA

Abstract
Different MW forms of the protein product of the yeast [Saccharomyces cerevisiae] mitochondrial gene var1 arise by a process of asymmetric gene conversion. These different forms can be accounted for by 2 DNA segments, .apprx. 36 and 57 base pairs long, present in 1 allelic form of the var1 structural gene, which can be inserted independently and at different frequencies into other var1 alleles.
