Homework Answers
Question 9
The correct path taken by the newly synthesized protein is
Rough ER->Golgi bodies->transport vesicle->plasma membrane.
Hence, option A is correct.
Question 10
As, the unicelluar organism have cell wall, flagella (use for locomotion) and most important peroxisome(only present in eukaryotes). Therefore, it is a motile eukaryote.Hence, option E is correct.
Question 11
The DNA is contain mainly in nucleus but few amount of DNA is present in mitochondria and chloroplast too. Hence, option d is correct.

Order the following statements to correctly describe the route of secreted protein as it is synthesized and secreted from a eukaryotic cell. A. The protein folds and undergoes modification within the rough ER. B. The protein travels within a membranous vesicle from the ER to the cis face of the Golgi apparatus. C. Translation begins on a ribosome. D. The protein travels toward the trans face of the Golgi, from which it is packaged into a secretory vesicle. E. The...

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
