Protein Synthesis

In this evaluation you need to

Part One:

Scientific method and Taxonomy

1. What is the order of classification going from complex to specific?
2. How does a scientific name show a degree of relatedness?
3. If a cell has organelles, what type of cell is it?
4. If a cell has not nucleus what type of cell is it?
5. What is the function of a cladogram?
6. How are Domains linked Kingdoms

Part Two

Evolution

1. What at the types of direct and indirect proofs for evolution?
2. When there is convergent what evidence could you use?
3. Homologous, Analogous and Vestigial structure, how do they apply to evolution?
4. What is an adaption? How is it linked to evolution?
5. What is the significance of movement between genes in populations?
6. How do finch populations in the Galapagos Islands show natural selection, divergent evolution and isolation mechanisms?
7. If two species show similar proteins or dna, are they directly related?
8. How are Darwin and Lamarck similar and different?

Part Three

DNA

1. Label all the structures that make up DNA ( sugar, phosphate and nitrogen base)
2. Know how information flows from DNA code to sequence of a protein
3. Transcribe DNA code to RNA (know to change Thymine to Uracil)
4. Identify complementary base pairs for DNA and RNA.

Short Answer Topics

Can you explain using a graph and or written paragraph the difference and significance of punctuated equilibrium verses gradual change? Which did Darwin support and why?

Can you explain why genetic drift, gene flow and natural selection all depend upon mutations?

Can you take a sample sequence of nitrogen bases as letters ( A,T,C,G) and convert that code into mRNA, transcribe the mRNA code into tRNA and solve what the amino acid sequence should be?

Can you explain the difference between reproductive isolation and geographic isolation?

Can you provide three functions for DNA?
