When a stop codon is in place at the ribosomal A site, a ________________ factor binds to the site instead of a new aminoacyl-tRNA. List two specific causes of DNA mutations. One of the ways chromatin remodeling occurs to allow gene expression is ____________________ of ______________ residues of histones. During translation, elongation factors EF-Tu and EF-G use hydrolysis of the energy molecule ________ to successfully complete their tasks The __________________________________ sequence is a consensus sequence (in prokaryotic mRNAs only) that signals...

15. Translation (RNA protein) has three main stages: initiation, elongation, and termination. a. Initiation occurs when the small ___________________ subunit binds to the ____ end of mRNA and is then joined by the large _________________ subunit (which has three sites called the A, P, and E sites). Once the complex is formed, the _______________ begins to read the mRNA in a ____ to ____ direction. When it reaches the first start codon (_________) a tRNA carrying the amino acid ______________________...

Please explain
Why is a cap added to MRNA, but not to 1RNA or RRNA? Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap. Transcription and processing of MRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and...
