P = Promoter DNA element. The hereditary material i.e. DNA (deoxyribonucleic acid) of an organism is composed of a sequence of four nucleotides in a specific pattern, which encodes information as a function of their order. Genomic organization refers to the linear order of DNA elements and their division into chromosomes.
American Teacher is a feature-length documentary created and produced by The Teacher Salary Project. Following the format of the book Teachers Have It Easy: The Big Sacrifices and Small Salaries of America’s Teachers, the film utilizes a large collection of teacher testimonies and contrasts the demands of the teaching profession alongside interviews with education experts and education ...
DNA profiling was developed in 1984 by British geneticist Sir Alec Jeffreys, [166] and first used in forensic science to convict Colin Pitchfork in the 1988 Enderby murders case. [167] The development of forensic science and the ability to now obtain genetic matching on minute samples of blood, skin, saliva, or hair has led to re-examining many ...

A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
DNA replication on the lagging strand is discontinuous. In lagging strand synthesis, the movement of DNA polymerase in the opposite direction of the replication fork requires the use of multiple RNA primers. DNA polymerase will synthesize short fragments of DNA called Okazaki fragments which are added to the 3' end of the primer. These ...
