this week we learned more about DNA. we made up a story about it or it could be scintific. mine was really bad. also we talked about messager and transfer RNA. transfer was the one that one that gave the ribosomes the code and the messanger RNA gave things to the other ribosomes. in DNA their are things called base pairs. they can only go with other base pairs.

DNA base pairs:
Adenine-> Thymine
Thymine->Adenine
Guanine->Cytosine
Cytosine->Guanine

RNA base pairs:
Adenine->Uracil
Uracil->Adenine
Guanine->Cytosine
Cytosine->Guanine

the difference between RNA and DNA is that DNA has a double helix or 2 sugar back bones. RNA only has a single helix or one sugar back bone.we also did some simulations that helped. this is basically what we talked about all week.
