Labeled antibodies are used as probes to detect proteins in: Hybrid capture assay. Northern blot. Southern blot. Western blot. | Western Blot |
RNA differs from DNA in that RNA: Contains thymine instead of uracil. Contains an H group instead of an OH group at its number 2 carbon. Is normally single-stranded. Is used to carry the genetic information of most viruses | Contains an H group instead of an OH group at its number 2 carbon. |
