Explain how DNA replicates.

Question description

Answer the following questions, in a total of 350 to 700 words.

• Describe the structure of DNA and the steps of protein synthesis.
• Describe the relationships between the following terms:
  • DNA
  • Chromatin material
  • Gene
  • Chromosome
• Use the following gene in protein synthesis:
  • TAGGACCATTTTAGCCCC
    • Show the mRNA.
    • Show the tRNA.
    • Name the amino acids that will be placed in the polypeptide chain.
• 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.
  • Explain how DNA replicates.
  • Describe the formation of the leading strand and lagging strand and include the enzymes involved.
  • Why do the legs replicate differently?
