Translation Obviously Not Transcription ,Transduction , or Transformation
How many strands of RNA make up a tRNA? • 1 • 2 • 3 • 4 • 5
What is being represented in the red, yellow, green and blue portions of this tRNA? • Hydrogen bonding • Ionic bonding • Nucleotide modification • Disulfide bonds • snRNP’s
Where does an amino acid attach to? • 5’ end • D loop • Anticodon • T loop • 3’ end
What amino will be “loaded” onto the attachment site • Threonine • Tryptophan • Lysine • Phenyalanine • Leucine
What amino will be “loaded” onto the attachment site • Threonine • Alanine • Lysine • Arginine • Glycine
What amino will be “loaded” onto the attachment site • Phenylalanine • Leucine • Glutamic acid • Lysine • Glycine
How many different types of tRNA’s are there? • 10 • 20 • 45 • 61 • 64
What is the name of the enzyme shown below? • Peptidyl tRNA Transferase • Amino-acyl tRNA Synthetase • Amino Acid RNA Transferase • ATP amino acidase
How does the enzyme know which amino acid to put on the 45 different tRNAs? • They have a piece of RNA that is complementary to the anticodon and amino acid. • The shape of the active site is complementary to the tRNA arm and amino acid. • An amino acid acts as an allosteric activator. • ATP allows for induced fit of tRNAs 64 different anticodons. • The nucleolus yells at it until it catalyzes the correct reaction.
Which of the following is NOT a component of the translation initiation complex? • Small ribosomal subunit • tRNA with a 3’ UAC 5’ anticodon • Primary transcript that was originally transcribed by RNA polymerase II. • Large ribosomal subunit • Peptidyl site in the large ribosomal subunit.
What was the energy source that brought all of these components together? • ATP • GTP • CTP • UTP • dATP • dGTP • dCTP • dTTP • FIRE
How many different types of RNA are shown here? • 1 • 2 • 3 • 4 • 5
