Large tandem repeats of grass frog (Rana temporaria) in silico and in situ.

ABSTRACT:

Background

Genomes of higher eukaryotes contain a large fraction of non-coding repetitive DNA, including tandem repeats (TRs) and transposable elements (TEs). The impact of TRs on genome structure and function and the importance of TR transcripts have been described for several model species. Amphibians have one of the most diverse genome sizes among vertebrates, attributed to the abundance of repetitive non-coding DNA. Consequently, amphibians are good models for the analysis of repetitive sequences, including TRs. However, few studies have focused on amphibian genomes.

Results

Bioinformatic analyses were performed to characterise the content and localisation of TRs in the sequenced grass frog Rana temporaria genome. By applying different bioinformatic approaches, 76 TR fam
