A double blind study is the most rigorous clinical research design because, in addition to the randomization of subjects, which reduces the risk of bias, it can eliminate or minimize the placebo effect which is a further challenge to the validity of a study.
Transcription by RNA polymerase. An RNA strand is synthesized in the 5â²âââ3â² direction from a locally single stranded region of DNA. (After E. J. Gardner, M. J. Simmons, and D. P. Snustad, Principles of Genetics, (more...).igure 10-6. Transcription of two genes. (a) RNA polymerase moves from the 3â² end of the template strand, creating an RNA strand that grows in a 5â²âââ3â² direction (because it must be antiparallel to the template strand).
RNA translation occurs on the ribosome. the ribosomes are outside of the nucleus attached to rough ER. this translation occurs with the aid of tRNA, transfer RNA, takes place on the ribosome, and results in protein synthesis. so to review, transcription happens in the nucleus and translation outside of the nucleus on a ribosome. all of this ...
