Map of clones and subclones on chromosome 1q21. (A) The YAC clone MNG1 was subcloned to cosmid YC11 or YAC MNG4. The λ subclones were derived from MNG4. The sequences of cosmid and λ subclones were compared to the sequences of genes in the GenBank database. The shaded boxes represent the genes at this locus. Genes shown above the line are transcribed left to right; MTX is transcribed in the opposite direction. (psMTX is not transcribed.) (B) Expanded map of λ clones, showing the EcoRI plasmid subclones used for sequencing.
