Missing from the table (which will be corrected in the next edition) is the incubation period of Ebola virus, which is 2 to 21 days. I would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur.The characteristic symptom of HIV-1 infection, immunosuppression, occurs much later. 1  Tweet. would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur.

DNA probe. 1. a laboratory-produced quantity of a known segment of labeled DNA that is used for finding matching DNA in a biological sample, as blood or hair, by the base-pairing of strands from both sources.2. a search or examination with such a DNA segment.1  Facebook.. a laboratory-produced quantity of a known segment of labeled DNA that is used for finding matching DNA in a biological sample, as blood or hair, by the base-pairing of strands from both sources. 2. a search or examination with such a DNA segment. 1  Facebook.
DNA microarray. In spotted microarrays ,the probes are oligonucleotides, cDNA, or small fragments of PCR products that correspond to mRNAs.Each probe contains a different, characteristic sequence that is specific to a different group of genes under study.These probes are then spotted onto glass substrate to form an array.n oligonucleotide microarrays, the probes are short sequences designed to match parts of the sequence of known or predicted open reading frames. Although oligonucleotide probes are often used in spotted microarrays, the term oligonucleotide array most often refers to a specific technique.
