BELL WORK: STUDENTS COMPLETE REPLICATION DRAWING ACTIVITY

​

​IS YOUR DRAWING EXACTLY LIKE THE FIRST IMAGE???

TODAY IT IS ALL ABOUT EXACT COPIES.
TODAY...WE WANT TO DISCUSS
DNA REPLICATION.

OBJECTIVE: STUDENTS CAN MODEL THE PROCESS OF DNA REPLICATION.

REPLICATION-THE ACTION OF COPYING OR REPRODUCING SOMETHING.




BEFORE MOVING ON....
LET'S REFLECT ON DNA...
WE ALREADY KNOW:
*DNA IS COPIED (REPLICATED) DURING *INTERPHASE BEFORE MITOSIS.
*DOUBLE HELIX (SHAPE)
*IN THE NUCLEUS OF EUKARYOTIC CELLS
*GENETIC MATERIAL
​*HAS NUCLEOTIDES WITH THE BASES:
       A-T / T-A AND C-G / G-C










LET'S WATCH THE DNA REPLICATION VIDEO...COLLECT INFORMATION FROM THE VIDEO ON THE HANDOUT SHEET.

​
​

​



NOW LET'S LOOK CLOSER AT THE DNA NUCLEOTIDES WITH.....A's, T's, C's and G'S... 

FLIP TO THE BACK OF THE
HANDOUT SHEET. 

ARE ALL OF THE STRANDS EXACTLY ALIKE? THEY SHOULD BE....

NOW YOU MAKE HALF OF A DNA AND SEE IF YOUR FRIEND CAN REPLICATE IT.
