Its principalfunction is to eliminate mRNA transcripts with prematurestop codons. Such faulty transcripts are detected duringtranslation and subsequently destroyed by removal of the 5′cap followed by degradation by a nuclease. Describe howpremature stop codons are detected and what type of errorcauses them.

Physicians are particularlyinterested in this antibiotic for treating pneumoniacaused by penicillin-resistant Streptococcus pneumoniae (also called pneumococci). To explore themechanisms by which pneumococci can developresistance to linezolid, you first want to identifylinezolid-resistant strains.

Transcription is the process cells use to copy information from DNA into messenger RNA copies. Part of the chromosome's tightly wound-up long strand of DNA is "loosened" to allow for RNA polymerase room to copy part of the DNA. Think of this as opening a page out of a giant book with thousands of pages to make a copy of just that one page. One side of the DNA strand is the template strand (or anti-sense strand) and is used by an enzyme called RNA Polymerase to create the messenger RNA. RNA Polymerase is directed by a bunch of proteins called transcription factors to the spot it needs to start copying. RNA Polymerase reads the template strand from the 3' end to the 5' end and creates a messenger RNA strand that is complementary to the template strand.
