The preponderance of protein sequence information is now derived from:
A) chemical sequencing (Edman method).
B) mass spectrometry.
C) mass spectrometry-mass spectrometry.
D) translating the nucleotide sequence of genes into codons, and thus amino acid sequence.
E) none of the above.

Question

Quizplus · Accepted Answer

The majority of protein sequence information is now obtained by translating the nucleotide sequence of genes into codons, which in turn gives the amino acid sequence. This is made possible by the many advances in genome sequencing technologies that have dramatically increased the availability of genetic information, allowing for the identification of genes that encode proteins in a wide variety of organisms.
