Which of the following statements best describes the initiation of translation? A tRNA with the anticodon, AUG, enters the ribosomal complex and binds to the mRNA at the A site. b) The large and small ribosomal subunits scan the mRNA in the 3'-5 direction until the promoter is reached. The mRNA containing the start codon, AUG, sits at the P site and forms a complex with the corresponding tRNA, and the large and small ribosomal subunits. d) The mRNA attaches...

* 1. Which of the following statements describes translation initiation in Eukaryotes: Initiation factors, a tRNAmet, and the ribosome's small subunit bind to the poly-A tail of mRNA. ✓ The ribosome's large subunit, tRNA, and P-site scan the mRNA for codons. ✓ The ribosome's large subunit binds to AUG codon on the mRNA. A ribosome binds to the C-terminus of an mRNA. Initiation factors, a tRNAmet, and the ribosome's small subunit bind to the 5'cap of mRNA. Initiation factors provide...

Which is incorrect about the initiation of translation? Select one: a. 30S subunit binds to mRNA first by recognizing the Shine-Dalgarno sequence on mRNA. b. In bacteria, most of the starting Met codon is specifically for N-formyl methionine (fMet). c. After fMet-loaded tRNA is bound, the 50S subunit binds to make the complete translational complex. d. A complete ribosome complex migrates on an mRNA until it finds the Shine-Dalgarno sequence. e. All of these

Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...

Place the events of Translation in bacteria into the correct order. The large ribosomal subunit associates with the small subunit and mRNA. The ribosome shifts along the mRNA in the 5' to 3' direction, moving the tRNA from the aminoacyl (A) site into the peptidyl (P) site. The tRNA in the peptidyl (P) site shifts to the E site and leaves the ribosome. The next charged tRNA enters the open aminoacyl (A site of the ribosome. Aminoacyltransferase attaches the amino...

1.) What happens to the translation initiation complex before the ribosomal subunit can be added? 2.) What are two ways aminoacyl tRNA synthetase ensures proper pairing between tRNA and amino acid? 3.) What stages of transcription or translation require GTP hydrolysis? 4.) When only non-hydrolyzable GTP tubulin dimers are available, how this affect the shrinking of microtubule filament?
