1
DNA Protein Synthesis Replication
2
DNA carries a code for proteins
3
What are proteins used for?
6
DNA protein
7
DNA protein Stays in nucleus made by ribosomes
8
DNA messenger protein
9
http://www.johnkyrk.com/DNAtranscription.html 1. One side of DNA is ‘transcribed’ to messenger RNA. http://www.wisc-online.com/objects/ViewObject.aspx?ID=AP1302 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.
