Q. Which of the following is an incorrect statement about the terminologies related to protein sorting?

View solution

Q. For many eukaryotic proteins, newly synthesized protein precursors have to be transported to specific membrane-bound compartments and be proteolytically processed to become functional.

View solution

Q. Once the proteins are translocated within the organelles, protease cleavage takes place to remove the signal sequences and generate mature proteins.

View solution

Q. The signal sequences have a _________ consensus but contain some specific features. They all have a ______ core region preceded by one or more positively charged residues.

View solution

Q. The signal sequences are typically _______ residues long, rich in _____ charged residues such as arginines as well as hydroxyl residues such as serines and threonines, but devoid of ______ charged residues.

View solution

Q. Chloroplast localization signals are also located in the __________ terminus and are about 25 to 100 residues in length, containing very few _______ charged residues but many hydroxylated residues such as serine.

View solution

Q. Chloroplast localization signals consist of two adjacent signal peptides, one for targeting the proteins to the stromaportion of the chloroplast before being cleaved and the other for targeting the remaining portion of the proteins to the thylakoids.

Q. Which of the following is untrue regarding the classic yeast two-hybrid method?

View solution

Q. An alternative approach to determining protein–protein interactions is to use a large-scale affinity purification technique that involves attaching fusion tags to proteins and purifying the associated protein complexes in an affinity chromatography column.

Q. Which of the following is untrue regarding the Predicting Interactions Based on Domain Fusion?

View solution

Q. When the two domains are located in two different proteins, to preserve the same functionality, their close proximity and interaction have to be preserved as well.
