DNA and the steps of protein synthesis.
Answer the following questions, in a total of 650 to 800 words.
• Describe the structure of DNA and the steps of protein synthesis.
• Describe the relationships between the following terms:
o DNA
o Chromatin material
o Gene
o Chromosome
• Use the following gene in protein synthesis:
o TAGGACCATTTTAGCCCC
Show the mRNA.
Show the tRNA.
Name the amino acids that will be placed in the polypeptide chain. (Use the codon table in Ch. 10, Figure 10.8A of Campbell Biology.)
• A gene will direct the making of polypeptide chains, and polypeptide chains form proteins. All enzymes are proteins. Therefore, how would you explain carrying
a gene for a trait that does not show up in the offspring?
• In order for DNA to pass genetic information to the next generation, DNA must replicate successfully. Mistakes in replication could result in major problems in
heredity.
o Explain how DNA replicates.
o Describe the formation of the leading strand and lagging strand and include the enzymes involved.
o Why do the legs replicate differently?
