You explained this experiment SO much better than my professor did. Thank you!

Sal, you are helping me so much... thank you

i'm loving these new biology videos. where are they listed on the khan academy website?

the cold spring harbour lab still maintains a little exhibit with Hershey and Chase's food blender

7:01 Laziness is my virtue. Can someone fix the captions from "int here" to "in there"?

this makes so much sense thank you!

shouldnt it be "infected the bacteria" and not * injected the bacteriophage * .

Every time I see a woman getting credit for scientific discovery I'm just like, "well maybe the world isn't so bad after all." :3 ^-^

Sulphur 35 is a isotope which is radioactive so u know sulpher is sulphur weather it is radioactive isotope or not thus if u provide cell only s35 then cell will incoporate in protein same for P32

Thanks for helping students always your videos are really good 😘😘

you saved my life thank you

Sir, I am looking for the answer to the question "how Avery, McCarty, and MacLeod cultured heat-killed S bacteria?" They may not cultured it. they may just start DNA isolation from heat-killed material (containing heat-killed bacteria). please explain the line "To do so, they began with large cultures of heat-killed S cells"

Wow thank you.

i love khan academy
