Today we began our understanding of cell division from Interphase through Cytokinesis. IF you were absent today you can easily print THESE NOTES and read pages 55-60 in your textbook for understanding. This week is all about understanding the phases, sequence, events, and purpose of cell division. Good deal!  Some of you were absent last week and may have missed the DNA notes. Read pages 61-62 and PRINT THIS
Here is James Watson to tell the story of this great discovery! Worth the watch for the drama and a chuckle. Today we learned more about DNA's structure as well as the functions. Next week we learn all about cell division and how DNA uses replication to copy the instructions, pair the chromosomes, line up in the middle of the cell, pull apart to two ends and finally form two new nuclei identical to the original one (that's mitosis!). This weekend you may choose to play the replication games HERE or HERE. You maybe want to watch THIS VIDEO about replication. Check back tomorrow for more information about the historical discovery of DNA. If you missed class today you may explore the RAP BATTLE OF WATSON/CRICK AND ROSALIND FRANKLIN... we added their information to our Giants of Science section. Such a dramatic discovery! 
I should have all your DNA models by now... if not make sure you finish at home or
if absent when we did them make the plan for next week to complete your model. Today we constructed our very own segment of DNA. Well, we made a model of DNA using construction paper to represent the 3 letter code of DNA with our own 3 letter coded initials. IF you were absent you will need to make this up during homebase study hall, at lunch, at PRIDE, or after school sometime this next week... check with me for what time works best. In these next few weeks we have much more to learn about this amazing molecule from who discovered it, how it copies itself in replication, how to "read" a strand so proteins are made, and how DNA controls our traits and heredity. An exciting few weeks ahead for sure!  Signups are February 5th ... season begins February 17th  Today we finally made it back to school for the year (I should have posted yesterday to just rinse and repeat Monday's post!)
Tonight a few of you need to write your SWYK from last Thursday/Friday or possibly finish the almond respiration lab (review this post if needed). Get all that work done tonight so we can start fresh and clean on DNA tomorrow. Tomorrow we shall build our own DNA strand personalized to your own initials. DNA is a personalized molecule as well... personalized to YOU! Get some rest tonight from the long day after a long break... or help shovel! It's good to be back to school thought, don't ya think? I do! The question is whether or not the snow will keep us on vacation... what do you think?  |
