E. coli. An E. coli RNA polymerase is composed of five subunits: two Î± subunits, and one for each Î², Î²', and Ï subunit. Î² (151 kD) and Î²' (156 kD) are significantly larger than Î± (37 kD). Several different forms of Ï subunits have been identified, with molecular weights ranging from 28 kD to 70 kD.n E. coli RNA polymerase is composed of five subunits: two Î± subunits, and one for each Î², Î²', and Ï subunit.

Probably everybody agrees with the statement that Tg is one of the temperatures within a glass transition region where the metastable melt transforms into glass in the course of its cooling and where glass transforms into metastable melt in the course of heating.
Normal Body Temperature. Body temperature is usually measured by a thermometer placed in the mouth, the rectum, or the auditory canal (for tympanic membrane temperature). The normal oral temperature is 37Â° Celsius (98.6Â° Fahrenheit); rectally, it is 37.3Â° Celsius (99.2Â° Fahrenheit).The tympanic membrane temperature is a direct reflection of the body's core temperature.These values are based on a statistical average.he normal oral temperature is 37Â° Celsius (98.6Â° Fahrenheit); rectally, it is 37.3Â° Celsius (99.2Â° Fahrenheit).
