Document Summary

Types of rna mrna--(messenger) intermediate molecules used for transfer the information from dna to protein. rrna--(ribosomal) functional rna molecules that are components of the ribosome. trna--(transfer) functional rna molecules that serve as adapters in translation. The enzyme rna polymerase binds to a specific site in dna (promoter) with the help of transcription factors http://highered. mcgraw- hill. com/sites/9834092339/student_view0/chapter16/transcription_complex_and_enhancers. htm l. Elongation and termination http://bcs. whfreeman. com/lodish5e/pages/bcs-main_body. asp? s=04000&n=00010&i=04010. 01&v=chapter&o=||&ns=0&t=&uid=0&rau=0: after the enzyme rna polymerase binds to the promoter, it catalyzes the production of an rna molecule, the base sequence of the rna produced is complementary to the base sequence of the. Dna template strand: transcription ends with a termination phase. Rna polymerase encounters a transcription termination signal that causes the rna to form a unique structure that help it to dissociate from the dna and from the rna polymerase. The following series of events defines information flow in the cell: Phenotypes physical features and functional traits or organism.
