Abstract: Embodiments described herein include a method and system for synchronizing clocks between coupled integrated circuits (ICs) in a computer system. According to an embodiment, a dedicated timing pin is provided on a first IC. The first IC configures a second IC to change a pin assignment, so that the second IC interprets a signal sent on the timing pin by the first IC and received on the reassigned pin as a request to transmit a return signal. The return signal is received on the timing pin. The return signal is used to determine whether timing should be adjusted by the first IC. In an embodiment a clock and data recover (CDR) circuit compares the signal sent to the signal received in order to make the determination. In an embodiment the first IC is a processor-based device, and the second IC is a memory device controlled by the first device.

Abstract: A DNA probe p13-1-25 is homologous to at least a portion of a hypervariable DNA region located on chromosome 19p13.2.fwdarw.19cen in the human genome. The DNA region displays extensive restrictive fragment length polymorphisms when digested with certain restriction endonucleases. Probe p13-1-25 is believed to have three closely linked lock (.alpha., .phi., .epsilon.). Loci .alpha. and .phi. each have two common alleles, whereas .epsilon. has at least 33 alleles, including a null allele. Unrelated individuals display unique fragment patterns on TaqI blots probed with p13-1-25. The probe can be used to produce a genetic "fingerprint" for establishing human identity, determining engraftment of bone marrow transplants, determining parentage, and otherwise mapping genes.

Abstract: A DNA probe pl-79 is homologous to at least a portion of a hypervariable DNA region located at chromosome lp36.3 in the human genome. The DNA region displays extensive restriction fragment length polymorphisms when digested with certain restriction endonucleases. Probe pl-79 is believed to have a repeated 39 base sequence CCTGGGGGTGNGNGTGCTGTTCCAGGCTGTCAGAGGCTC, and can be used as a genetic "fingerprint" to establish human identity, determine engraftment of bone marrow transplants, determine parentage, and otherwise map genes.

Abstract: A DNA probe p144-D6 is homologous to at least a portion of a hypervariable DNA region located on chromosome 17(17p13) in the human genome. The DNA region displays a restriction fragment length polymorphism when digested with certain restriction endonucleases. Unrelated invididuals often display unique fragment patterns on Southern blots probed with p144-D6. The probe can be used to produce a genetic "fingerprint" for establishing human identity, determining engraftment of bone marrow transplants, determining parentage, and otherwise mapping genes.

Abstract: A DNA probe p79-2-23 is homologous to at least a portion of a hypervariable DNA region located on chromosome 16q22.fwdarw.q24 in the human genome. The DNA region displays a restriction fragment length polymorphism when digested with certain restriction endonucleases. Unrelated individuals display unique fragment patterns on Southern blots probed with p79-2-23. The probe can be used to produce a genetic "fingerprint" for establishing human identity, determining engraftment of bone marrow transplants, determining parentage, and otherwise mapping genes.

Abstract: A DNA probe which is homologous to at least a portion of a hypervariable DNA region D2S3 located at chromosome 2q35-37 in the human genome. The DNA region displays restriction fragment length polymorphism when digested with certain restriction endonucleases. The probe, p5-1-25, can be used to produce a genetic "fingerprint" to establish human identity, determine engraftment of bone marrow transplants, determine parentage, and otherwise map genes.
