The beneficial uses of bacterial toxins in medicine are more and more used lately. For example, Botulinum toxin is a toxic protein produced by the bacterium Clostridium botulinum which has paralytic effects (injection of this toxin into muscle relax specific muscles). Botulinum toxin accomplishes his effects on the neuromuscular junction where he prevents the release of the neurotransmitter acetylcholine (Ach). Utilization of this toxin is in the treatment of various muscle spasms. It is also used in the treatment of migraines. Diphtheria toxin is also one of the toxins used for medical purposes for the treatment of cutaneous and non-Hodgkin T-cell lymphomas. <span>Some bacterial toxins can be used in the treatment of tumours. For example, immunotoxin, which is protein made by fusion of modified antibody and toxin.The antibody binds to an antigen on the target cell, the toxin then enters via endocytosis and kills the cell. Commonly used bacterial toxins in immunotoxins are Diphtheria toxin and the Pseudomonas exotoxin.</span>
Answer
The difference is that a tropical storm has wind speed up to 73mph, once it exceeds this then it become a hurricaneTornadoes are usually very short and can last up to an hour, but a hurricane can last up to three weeks. A hurricane almost always forms over sea while a strong tornado usually forms over land

Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.
