Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien

Which of the following statements about translation is false? In eukaryotes, the 5' cap and the 3' poly(A) tail are involved in translation initiation. Peptidyl-transferase activity during translation is the property of a ribozyme. A base at the first position of an anticodon on the tRNA would pair with a base at the third position of the mRNA. The growing peptide chain is transferred from the tRNA in the P site to the tRNA in the A site. Ribosomes move along an mRNA in the 3’ → 5' direction.
