Class A (type D) CpG ODNs (CpG-A ODNs) contain a central palindromic phosphodiester (PO) CpG sequence and a PS-modified 3â poly-G tail. The poly G tails form intermolecular tetrads that result in high molecular weight ordered structures.
Why does a tornado form when cold and hot air meet? The collision of warm and cold air is not the direct cause of a tornado, nor is it absolutely necessary. When a cold air mass pushes into a warm air mass (this is called a câ¦old front) the warmer, less dense air is forced upwards.
Well 330C is hot, 330F is cold. That depends if it is 33 degrees Celsius or 33 degrees Fahrenheit. If it was 33 degrees C then it would be hot because it is around 85 degrees â¦ F. If it was 33 degrees F....then it would be darn cold.
