Question

1. describe central dogma of biology.

2. list and describe two examples of evidence showing species evolve overtime.

3. can you see evolution occur in an organism why or why not?

Answer 1

1. Central dogma basically describes the two processes

1) TRANSCRIPTION

2) TRANSLATION

TRANSCRIPTION is the process of DNA to RNA and TRANSLATION describes the process from RNA to PROTEINS.

TRANSCRIPTION TRANSLATION DAT → L'UN → 0000 ONA mRNA Protein

2. list and describe two examples of evidence showing species evolve over time.

1) Stages in the evolution of the horse

Equus (recent) Pliohippus (4 mya) Hipparion (8 mya) Mesohippus (25 mya) Hyracotherium (50 mya)

2) Darwin's Finches

Common ancestor G. fortis G. conirostris G. magnirostris Descent with hybridization Hybrid male Hybrid female Big Bird lineage

3. Can you see evolution occur in an organism why or why not?

No, evolution cannot be seen in an organism, it takes place in whole species over period of time.

if we see a change in some organism but not in others that is just because of mutation.
