Hello bio period 2!

Today in biology class we checked in 13.4 notes and got a stamp.

Then Mrs. Stein introduced us to mRNA and tRNA, and showed us

how to convert a strand of DNA into a strand of mRNA. Simple right?

G pairs with C and A pairs with T? ERROR! We also learned today that

there is no (T)thymine in RNA. The substitute for T in RNA is U; Uracil.

We converted the DNA strands into RNA with this new information. Your

assignment, should you choose to accept it... is the Tribune article

that is due Monday the 21st. Don't forget to study for the test on

Monday and also the 13.1 and 13.2 flow map is due tomorrow.

This message will self destruct in 30 seconds...

Sam Carter will be the next scribe!
