Intrachromosomal movement of genetically marked Saccharomyces cerevisiae transposons by gene conversion. 1984

G S Roeder, and M Smith, and E J Lambie

In this paper, we describe the movement of a genetically marked Saccharomyces cerevisiae transposon. Ty912(URA3), to new sites in the S. cerevisiae genome. Ty912 is an element present at the HIS4 locus in the his4-912 mutant. To detect movement of Ty912, this element has been genetically marked with the S. cerevisiae URA3 gene. Movement of Ty912(URA3) occurs by recombination between the marked element and homologous Ty elements elsewhere in the S. cerevisiae genome. Ty912(URA3) recombines most often with elements near the HIS4 locus on chromosome III, less often with Ty elements elsewhere on chromosome III, and least often with Ty elements on other chromosomes. These recombination events result in changes in the number of Ty elements present in the cell and in duplications and deletions of unique sequence DNA.

D011995 Recombination, Genetic Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses. Genetic Recombination,Recombination,Genetic Recombinations,Recombinations,Recombinations, Genetic
D004251 DNA Transposable Elements Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.

D004271 DNA, Fungal Deoxyribonucleic acid that makes up the genetic material of fungi. Fungal DNA
D005785 Gene Conversion The asymmetrical segregation of genes during replication which leads to the production of non-reciprocal recombinant strands and the apparent conversion of one allele into another. Thus, e.g., the meiotic products of an Aa individual may be AAAa or aaaA instead of AAaa, i.e., the A allele has been converted into the a allele or vice versa.

D012441 Saccharomyces cerevisiae A species of the genus SACCHAROMYCES, family Saccharomycetaceae, order Saccharomycetales, known as "baker's" or "brewer's" yeast. The dried form is used as a dietary supplement.
