The Cell Cycle

Genetic Information is bundled into packages of ___________ known as ___________

• chromosomes, DNA

• RNA, RNA

• DNA, chromosomes

• centrioles, centrioles

Check all that apply: What are some features of prokaryotic cells?

• lack of membrane bound nucleus

• DNA in cytoplasm

• single circular chromosome

• membrane bound nucleus

• multiple chromosomes

Check all that apply: What are some features of eukaryotic cells?

• lack of membrane bound nucleus

• DNA in cytoplasm

• single circular chromosome

• membrane bound nucleus

• multiple chromosomes inside the nucleus

In eukaryotic cells, DNA is packaged with proteins into structures called chromosomes. What advantage do chromosomes provide the cell?

• they allow all genes to be expressed at the same time

• they allow random distribution of genes when the cell divides

• they ensure equal division of genetic material when the cell divides

• they eliminate the need for a nucleus

What is the cell cycle?

• Events leading up to protein synthesis in a cell
• Repeating sequence of events where cells grow and divide
• Steps that describe how plants perform photosynthesis
• Repeating events where cells evolve into new species
