Design an experiment to test if a protein really has a signal sequence that can target it to the nucleus. - Use GFP so you can watch the protein move in real time Describe an experiment to show that a candidate sequence is necessary for nuclear import. - Using a protein that normally enters the n...

Describe the signals and mechanisms required for import into the peroxisome. - -peroxisomal targeting sequence -peroxisomal import machinery (Pex5 receptor- first thing that binds on and recognizes signal sequence) Describe the functions of the SRP (signal recognition particle). - -Recognizes...

What are the main organs affected by cystic fibrosis? - Lungs, any organ that has epithelial cells, mucus, and secretory system which requires regulation of that mucus Describe the main function of the CFTR protein and how it is regulated. - responsible for regulating the proper flow of chloride ...

What is the molecular genetic definition of a gene? - A gene is a section of genomic DNA that codes for a function product and includes all of the sequences that regulate its expression. Is it possible to have a mutation that normally causes disease and not show any symptoms? Explain your answer...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments: movement microtubules: transport of cellular materials intermediate: support What are the main similarities and differences between the three components of the cytoskeleton? - all are impo...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments (actin): sense the environment and direct movement Intermediate Filaments: maintain cell shape/structure, anchor organelles Microtubules: for transport What are the main similarities and di...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments: made of actin; determines the shape of cell surface and is important for the movement of the cell Microtubules: made of alpha and beta dimers ; act as tracks for vesicles and other properti...
