29) Which one of the following statements about RNA processing is correct?
A) Exons are cut out before mRNA leaves the nucleus.
B) Ribozymes may function in RNA splicing.
C) RNA splicing can be catalyzed by TRNA.
Transcribed Image Text:34) What would be the consequence of a mutation in a bacterial cell that produces a defective
aminoacyl-tRNA synthetase that attaches a lysine instead of the normal phenylalanine to tRNAs
with the anticodon AAA?
A) None of the proteins in the cell will contain phenylalanine.
B) Proteins in the cell will include lysine instead of phenylalanine at amino acid positions
specified by the codon UUU.
C) The cell will compensate for the defect by attaching phenylalanine to tRNAs with lysine-
specifying anticodons.
