Biology Lecture Quiz 12

What molecule indirectly provides the energy for translation?

ATP

Which of the following statements about RNA processing in eukaryotes is INCORRECT?

Introns are simply excised out of pre-mRNA to produce the mature mRNA.

The most common eukaryotic ribosome carries out its function in the

cytosol.

Because more than one codon can specify the same amino acid, the genetic code is said to be

degenerate

Which of the following statements about tRNA is FALSE?

functional tRNAs have been spliced by splicesomes.

What factors are recognized by the cell in order to recognize the stop codon and disassemble the translation machinery?

release factors

A defective ribosome would have the MOST detrimental effect on what processes would a defective ribosome have the most detrimental effect?

translation

Because of the abundance of ribosomes, translation is NOT an energy costly process for the cell.

False

The termination of translation occurs when a release factor recognizes the stop codon.

True

The molecule mRNA, which contains the information to make a polypeptide, is constructed from a DNA template.

True
