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 oroperon in genomic DNA during translation
(B) Upstream open reading frames generally hinder translation of the main openreading frame (ORF)
(C) Ribosome density along ORFs can be studied with high resolution by sequencingof ribosome-protected mRNA footprints, a method known as ribosome footprinting.
(D) Mass spectrometry-based methods can provide estimates of synthesis anddegradation rates for a substantial fraction of proteins.
(E) The direct method for analysis of the de novo protein synthesis is to detect theisotope-labeled amino acids incorporated into newly synthesized proteins.
