Why did heat kill the S bacteria in the Griffith experiment?

How does it suggest that it was not a chemical poison released by the S bacterias?





also, what is transformation?





just answer one if you'd like. =)


thanks!

Why did heat kill the S bacteria in the Griffith experiment?
very complex experiment


Griffith believed polysaccharide coating on the bacteria somehow caused the illness and knowing that polysaccharides are not affected by heat, Griffith then used heat to kill some of the S strain bacteria and injected those dead bacteria into mice. Because the new mice didn't die, he knew the disease wasn't caused by polysaccharides (because they wouldn't have been effected by the heat)





there are sooo many definitions for a transformation


You can transform power from high voltage to low voltage and vice versa


you can transform sets of data that isn't inherently normal by taking the log of the data or squaring it, in order to make it normal





I assume you are talking about the genetic transformation. That is when to implant the plasmid of a bacteria or another vector, into a host cell. Also known as the genetic alternation from introduction, uptake, and expression of foreign dna
