Transcription Notes/Daily Questions/Activities

The past TWO day's we have been going through transcription using a variety of methods.  Here were the daily questions for both Wednesday and Thursday

Wednesday the 25TH (NOT the 24th sorry!!!)

We used our K'nex Models from before to build both a complementary DNA Strand along with the corresponding mRNA strand


First you made your Double Stranded DNA molecule using the Template DNA I gave today
Using the DNA base pairing rules you Matched Ts with As and Gs with Cs

NEXT you started to TRANSCRIBE the message found in the DNA.  This means you started to build your RNA molecule.  Some differences:  FIRST, the sugar is RIBOSE instead of Deoxyribose.  With our models that was shown by using the orange backbone pieces.  SECOND - Thymine on the DNA side is still paired with Adenine on the RNA side, but ADENINE now is paired with URACIL (NOT thymine).  With our models we see that as a PURPLE nucleotide.

Finally, the DNA is zipped RIGHT back up (just like we would close our instruction manual) and the RNA is released. 

After doing that ourselves I had you watch the first 2 minutes of the following video which shows you a MUCH more detailed look at what goes on at the sub-cellular level.

Some of the notes we used to go through this section (all of this was done in your book work so you didn't have to WRITE any of these notes down - you just updated the intro book work assignment)
