He took a few cautious steps toward the cave.

Nucleotide sequences of 71 TA systems from each genome were concatenated in ‘supersequence’ (supergene), and the resulting 173 long supersequences were aligned with each other using Clustal W ver. 2.1.

Until that moment, it had not really occurred to me — or my mothers, even though one is an ObGyn — that I might have half siblings out there.

There are ~80 genes in the C elegans genome coding for miRNAs that are twenty-one to twenty-four nucleotides long.
