Biological assymmetries and the fidelity of eukaryotic DNA replication

Article Abstract:

The fidelity of semi-conservative deoxyribonucleic acid (DNA) replication in eukaryotes is influenced by the presence of a particular DNA polymerase, its position on the DNA sequence, and the error type, i.e. base substitution, misinsertion, frameshift error, etc. The concentration of deoxyribonucleoside triphosphates and DNA sequence heterogeneity are also critical factors affecting replication fidelity.

Mechanisms of genomic rearrangements and gene expression changes in plant polyploids

Article Abstract:

Researches studying the origin and forms of polyploidy among plants for a better understanding of genomic and gene expression changes in polyploidy are reviewed, and the results of genomic-wide gene expression analyses are summarized. Allopolyploidy facilitates study of the genetic and epigenetic mechanisms of interaction between genes with divergent regulatory paths, orthologous genes and their products.
