Sickle-cell disease is a disorder that results in malformed hemoglobin molecules. What is the result of this in terms of hemoglobin function? Multiple Choice Hemoglobin has a reduced ability to bind to and transport oxygen in red blood cells. Hemoglobin has an increased ability to bind to and transport oxygen in red blood cells. Hemoglobin has an increased ability to bind to and transport carbon dioxide in red blood cells. White blood cells begin to pick up hemoglobin molecules instead and this decreases their ability to function in the immune system as intended.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
