1 DNA Protein Synthesis Replication

2 DNA carries a code for proteins

3 What are proteins used for?

4

5

6 DNA protein

7 DNA protein Stays in nucleus made by ribosomes

8 DNA messenger protein

9 1. One side of DNA is ‘transcribed’ to messenger RNA. 2. Messenger RNA is ‘translated’ to make proteins.

11 Replication: making copies of DNA so cell can divide into two new cells

12 Replication in Prokaryotes

13 Replication in Prokaryotes

14 Replication in Eukaryotes (they have a nucleus) Mitosis

15 Meiosis This replication makes Sperm or Egg cells for reproduction. Note they are all different.

16 Asexual reproduction No mixing of DNA You get the same organism

17 Sexual reproduction DNA is mixed to make new organism Egg and Sperm Plants

18 Sexual reproduction DNA is mixed to make new organism Egg and Sperm Fungi

19 Sexual reproduction DNA is mixed to make new organism Egg and Sperm Animals

20 Sexual reproduction DNA is mixed to make new organism Egg and Sperm Humans are Animals

21 Some organisms reproduce in different ways for different reasons.

23 Everything is fine. No reason to change.

24 Everything is fine. No reason to change. Tsunami or big waves. Coral is in pieces.

25 Everything is fine. No reason to change. Tsunami or big waves. Coral is in pieces. Environment changes. Rapid evolution needed.
