Essential Question: How do cells make proteins Essential Question: How do cells make proteins? Investigation Question: How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Investigation 1 Claim: All cells contain genetic information in the form of DNA. Eukaryotes have a nucleus where the chromosomes coil up the genes of DNA. Prokaryotes do not have a nucleus, but do have genes. Terms: Prokaryote, Eukaryote, Nucleus, Chromosome, Gene, DNA

Sequence of Terms Cell Types Eukaryotes Prokaryotes Nucleus Chromosome Genes Genes DNA DNA

How does the evidence justify the claim that all cells contain DNA? How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Evidence: Figure 1.1 Justification How does the evidence justify the claim that all cells contain DNA? Terms: DNA, Eukaryote, Prokaryote

How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Evidence: Figure 1.1 Justification How does the evidence justify the claim that all cells contain DNA? The evidence justifies the claim that all cells contain DNA by figure 1.1 showing Eukaryotes and Prokaryotes having DNA in the form of chromosomes.

How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Evidence Figure 1.2 Justification How does the evidence justify the claim that Eukaryotes have a nucleus where the chromosomes coil up the genes of DNA. Prokaryotes do not have a nucleus, but do have genes? Terms: Prokaryote, Eukaryote, Nucleus, Chromosome, Gene, DNA

How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Evidence Figure 1.3 Justification How can you justify that these cells are Eukaryotes or Prokaryotes that contain DNA? Terms: Prokaryote, Eukaryote, Nucleus, Chromosome, Gene, DNA

Investigation Question: How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Claim: All cells contain genetic information in the form of DNA. Eukaryotes have a nucleus where the chromosomes coil up the genes of DNA. Prokaryotes do not have a nucleus, but do have genes. Justification: All cells contain genetic information in the form of DNA, but are accessed differently because Use Justification 1, 2, and 3 from your notes. Evidence: Use the evidence presented (1.1 – 1.3) to justify the claim stated above.

Investigation Question: How are DNA molecules accessed differently in Eukaryotes versus Prokaryotes? Claim: All cells contain genetic information in the form of DNA. Eukaryotes have a nucleus where the chromosomes coil up the genes of DNA. Prokaryotes do not have a nucleus, but do have genes. Justification: All cells contain genetic information in the form of DNA, but are accessed differently because figure 1.1 shows that Eukaryotes and Prokaryotes have DNA in the form of chromosomes. In addition, figure 1.2 clearly shows Eukaryotes have a nucleus that contain coiled up chromosomes of DNA and prokaryotes do not have a nucleus, but do have DNA. Finally, figure 1.3 shows that the top picture are Eukaryotes because they clearly have a nucleus and the bottom picture are Prokaryotes because they have circular DNA without a nucleus.
