It is the site occupied by incoming aminoacyl tRNAs. It is surrounded by alpha-helices of ribosomal proteins. It is where the amino group on the growing polypeptide chain is available for peptide bond formation. It is where amino acids are affixed to tRNAs, producing aminoacyl tRNAs.
It is where peptidyl tRNAs reside. It is where the promoter resides. It is the site where peptide bond formation takes place. It is the site where the growing polypeptide chain is phosphorylated.
a protein that helps newly translated proteins fold into their proper 3-D configuration a protein that is a component of the large ribosomal subunit, and that assists with peptide bond formation a protein that recognizes the promoter and guides the binding of RNA polymerase a protein that guides newly translated proteins to their correct destination in the cell
rRNAs tRNAs mRNAs the small RNAs found in snRNPs
the part of a tRNA that accepts an amino acid, via a reaction catalyzed by tRNA synthetase the part of an RNA message that signals the termination of translation the part of an RNA message that signals the start of translation the part of a tRNA that binds to a complementary codon in mRNA
How does RNA polymerase "know’’ when to terminate transcription? Does RNA polymerase act alone to initiate transcription, or are other proteins involved? How does RNA polymerase "know" which strand of DNA acts as the template? How do sigma proteins bind to RNA polymerase?
