Which is the happy G-CAT?

⋇To understand replication, what do I need to know?

Replication and

the four DNA bases.

Guanine

Cytosine

Adenine

Thymine

G-CAT

3. G-CAT helps one remember the four nitrogen bases of DNA:

Guanine, Cytosine, Adenine, and Thymine

4. A pair of base makes up each

step/rung of the DNA ladder;

G⇿C and A⇿T pairs only.

(AT is a word)

A pair of base makes up each

step/rung of the DNA ladder.

If you know one side of the DNA

ladder, you can determine the

other side. Applying this concept:

G-C and A-T pairs only.Given that one side of the ladder is; What is the other side of the ladder:

CCGGTTAA

?

5. A cell’s genetic material is copied during DNA replication.

Original Unzipping Two Replicated Copies

Note: G pairs with C and A pairs with T every time.

6. A cell’s genetic material is copied during

DNA replication.

4th Chapter Test Review (SNB page 32)

7. Photosynthesis is how plants/autotrophs create their food.

Chloe Chloroplast

only works in plants.

8. Photosynthesis benefits

animals/heterotrophs

by creating food

to be eaten.

5. What sugar and oxygen producing process occurs in a leaf?

Photosynthesis (glucose is a simple sugar)

9. What are the two products of photosynthesis?

(glucose is a simple sugar)

10. Leaf cells use the energy in sunlight to make…

(glucose is a simple sugar)

11. Capturing the energy in sunlight and using it to produce food is the main function of …

Chloe the chloroplast

makes the best

sugar cookies using

glucose.

12. Respiration is the process cells use to get …… from food.

13. The three products of respiration are ……

14. Mitochondria convert the energy in sugars into a form of energy the cell can use.

(Converts food energy into cell energy)

15. Photosynthesis makes sugar and respiration breaks sugar down, so the processes are opposite.

16. The main purpose of cell division is to increase the number of cells in an organism.

17. DNA replication occurs before

a cell divides because each

daughter cell will need a complete

copy of the DNA.

4th Chapter Test Review (SNB page 32)

18. In mitosis, the parent cell’s nucleus divides into two new nuclei.

In cell division, the parent cell divides into two daughter cells.

19. Chromosomes separate at their centromeres during anaphase of mitosis.

20. The process by which a plant cell becomes a leaf, stem, or root cell is called…

Differentiation of cells allows cells to become root, leaf and stem cells. (Replicate this slide.)

Replicate this slide:

DNA Bases and Replication (how DNA copies are made)

Original Unzipping Two copies

C and G make a step or rung.

A and T make a step or rung.

(G-CAT will help you remember)

Bell Work 3/19 (Use complete sentences /SNB page 31)
