A protein factor required to recognize certain transcription termination signals in Escherichia coli . Ribosomes are made up of two non-identical subunits each consisting of a different rRNA and a different set of proteins. A single-stranded nucleic acid similar to DNA but having ribose sugar rather than deoxyribose sugar and uracil rather than thymine as one of the pyrimidine bases. May also sometimes involve insertion of cytidines and possible deletions of bases. In this technique, the probe is labeled, either radioactively or by chemically attaching a fluorochrome visualised by fluorescence or an enzyme that can convert a substrate to a visible dye.
Radioactive probe is detected by autoradiography.
Fluorochrome is detected by fluorescence microscopy. They are the simplest known phages. An enzyme that catalyzes the synthesis of an RNA strand from a DNA template. The enzyme that polymerizes RNA by using DNA as a template. It can also act as a primase initiating DNA replication.
