STCs
An STC is a short stretch of sequence read from one end of the human DNA insert in a clone. BAC clone STCs can be useful in a number of ways. First, STCs help researchers expand contigs, as outlined in the article. Second, when the insert length is determined, the STC spacing helps verify the contiguous sequence created by assembly software. Third, BACs with STCs serve to physically define and thus "capture" gaps that occur when sequencing biochemistry is stalled by occasional difficult-to-read stretches of DNA sequence. Finally, STC reads can be used for the design of STSs.
STSs
An STS is a DNA segment that can be copied repeatedly by PCR without amplifying unwanted DNA regions from the source genome. STS markers have been used by members of the International RH Mapping Consortium to construct the RH maps that complement contig building. STSs generated from BAC STC reads are helping to enrich RH maps. Conversely, a mapped STS can be used to isolate a BAC (or any DNA clone type) from a library of clones representing a genome.

The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome. See Timeline for more HGP history.
Published from 1989 until 2002, this newsletter facilitated HGP communication, helped prevent duplication of research effort, and informed persons interested in genome research.
