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

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. 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.

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. 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.
