Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as EtBr , which is also an abbreviation for bromoethane.thidium bromide is thought to act as a mutagen because it intercalates double stranded DNA (i.e., inserts itself between the strands), deforming the DNA. This could affect DNA biological processes, like DNA replication and transcription.
DAYS IN EACH MONTH. 30 days hath September, April, June and November, All the rest have 31, Excepting February alone (And that has 28 days clear, With 29 in each leap year). The number of days in each month has remained unchanged for 2000 years (since 45 B.C. in fact, when Julius Caesar introduced the Julian Calendar). Here's a well-known mnemonic rhyme which has been in existence for over 400 years, to indicate the exact number of days in each different month:
Use the Days From Date calculator. April 11th, 2016 is a Monday. It is the 102nd day of the year, and in the 16th week of the year (assuming each week starts on a Sunday), or the 2nd quarter of the year. There are 30 days in this month. 2016 is a leap year, so there are 366 days in this year.oday is October 14, 2015 so that means that 180 days from today would be April 11, 2016. You can check this by using the date difference calculator to measure the number of days from today to Apr 11, 2016.
