試題詳解

7. Which of the following descriptions about protein translation is not correct?
(A) Terminator is a section of nucleic acid sequence that marks the end of a gene or operon in genomic DNA during translation
(B) Upstream open reading frames generally hinder translation of the main open reading frame (ORF)
(C) Ribosome density along ORFs can be studied with high resolution by sequencing of ribosome-protected mRNA footprints, a method known as ribosome footprinting.
(D) Mass spectrometry-based methods can provide estimates of synthesis and degradation rates for a substantial fraction of proteins.
(E) The direct method for analysis of the de novo protein synthesis is to detect the isotope-labeled amino acids incorporated into newly synthesized proteins.
