Answer:
A. True
Explanation:
Hemoglobin is a protein and has two distinct types of polypeptide chains. These are called the alpha and beta subunits. The gene that code for the beta chain undergoes a mutation in a single base that causes sickle cell anemia. Here, adenine base in the genetic code for glutamic acid is substituted with a thymine base.
The genetic code for glutamic acid in the beta chain gene is GAG. The "A" is replaced with "T" and the new code "GTG" codes for valine. Therefore, the mutated hemoglobin has valine in place of glutamic acid. This makes these mutated protein molecules to form aggregates resulting in a change in the shape of RBCs carrying them.
Pglo is a plasmid.it has a gene for a protein that is bioluminescent.positive pglo bacteria have this plasmid while negative pglo bacteria do not
<span>This is a great question and I would love to hear what a roller coaster designer / engineer thinks makes a successful roller coaster. Until they show up, though, you've just got me.For me a successful roller coaster is one that fills me with dread as it makes the slow climb up the track, and then converts that dread into pure adrenaline as it takes me down and around. It's the one that makes your stomach drop as you're in freefall and makes your heart skip a beat as you take a corkscrew loop. Some roller coasters are open at the bottom so your legs dangle off. Some go backwards through a corkscrew. Those are fun additions.What I'm saying is that a good roller coaster is one that floods you with emotions as you're riding it - think about the Mummy ride at Universal Studios. It's not a particularly crazy coaster as far as thrill rides go, but the design of the ride itself is meant to fill you with anxious dread as you wait for something to happen and then launches you at breakneck speed when you least expect it. That's a good roller coaster, and I'm not even sure you'd actually call it a roller coaster.Well that's me ^.^ I hope this helps</span>
The answer is True.
Amoebas, Paramecia, and Euglenas are all types of protist that can reproduce asexually through binary fission. This is the most common form of reproduction in prokaryotes. The reproduction occurs in a single cell. The cell divides into two nearly equal sized along with its genetic material.
