Question
15. Proteomics allows researchers to: A) examine where a protein is located within the cytosol of a cell. B) compare thousands of samples from different people in the same experiment. C) examine which proteins differ in abundance between a normal sample and a disease sample. D) use antibodies to label specific proteins on an SDS-PAGE gel 16. Mass spectrometry techniques are used in proteomics for all of the following purposes EXCEPT: A) identification of thousands of proteins' amino acid sequences within a single cell. B) characterization of proteolytically digested pieces of proteins from the sample. C) identification of all the protein complexes present in certain yeast species. D) identification of proteins within each organelle in liver tissue.Explanation / Answer
15) Answer is :c) examine which proteins differ in abundance between a normal sample and a disease sample.
EXPLANATION :
Proteomics is defined as study of amounts, modifications, interactions, localization, functions of all or subsets of proteins.
Proteomics analyses various human diseases and mechanisms of initiation and progression of the disease. As disease is alterations in protein expression levels. So, studying the change in the abundance of proteins between different cellular states (normal and diseased states), proteomics gives basis of protein target identification and treatment of disease.
16) Answer is : D) identification of proteins within each organelle in liver tissue.
EXPLANATION:
All are correct except identification of proteins within each organelle in liver tissue.
