More specifically, we study the topics of telomere biology, cellular immortality, repetitive DNA, genome stability, genome silencing and small RNAs using the nematode Caenorhabditis elegans as a model system. C. elegans has a relatively compact ~100 MB genome whose sequence is completely assembled. … Read more
