Which statement below correctly compares prokaryotic and eukaryotic cells? Prokaryotic cells are larger in size than eukaryotic cells. Prokaryotic cells are single-celled and have cell walls, but eukaryotic cells are multicellular but don’t have cell walls. Both prokaryotic and eukaryotic cells have membrane-bound organelle such as nuclei and mitochondria. Both prokaryotic and eukaryotic cells have cell membranes and DNA or RNA. Prokaryotic cells can tolerate high pH environments better than eukaryotic cells. The Elements of Life In biology, the elements of life are the essential building blocks that make up living things. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. These elements form the basic building blocks of the major macromolecules of life, including carbohydrates, lipids, nucleic acids and proteins. Carbon is an important element for all living organisms, as it is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. Even the cell membranes are made of proteins. Carbon is also used to construct the energy-rich molecules adenosine triphosphate (ATP) and guanosine triphosphate (GTP). Hydrogen is used to construct the molecules water and organic compounds with carbon. Hydrogen is also used to construct ATP and GTP. Nitrogen is used to construct the basic building blocks of life, such as amino acids, nucleic acids, and proteins. It is also used to construct ATP and GTP. Oxygen is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. It is also used to construct ATP and GTP. Phosphorus is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. In this worksheet, we will practice describing the structures that contain DNA within prokaryotic cells. Q1: Which of the following statements correctly compares the DNA of eukaryotic cells with the DNA of prokaryotic cells?
Q2: For the following statements about the structure of DNA in prokaryotes, state whether they are true or false. Chromosomal DNA is linear in shape.
Chromosomal DNA is found within the nucleosome.
Extrachromosomal DNA is found in the form of small, circular plasmids.
Q3: Where in a prokaryotic cell is the chromosomal DNA contained?
Q4: Which of the following best describes prokaryotic plasmids?
Q5: The majority of DNA in prokaryotes is chromosomal DNA. Which of the following best describes the structure of this chromosomal DNA?
Q6: Which of the following statements about DNA in prokaryotic cells is correct?
Q7: Mitochondria, organelles found in eukaryotic cells (shown in the figure), have their own circular loops of DNA. According to the endosymbiotic theory, what does this suggest about the evolution of mitochondria?
Q8: The diagram provided shows the simplified structure of a bacterial cell. Which letter indicates the chromosomal DNA?
Q9: The diagram provided shows a simplified structure of a bacterial cell. Which letter indicates a plasmid?
Q10: Chloroplasts, organelles found in plant cells, have their own DNA that forms circular strands. According to the endosymbiotic theory, what does this suggest about the evolution of chloroplasts?
This lesson includes 30 additional questions for subscribers. What statement correctly compares prokaryotic and eukaryotic cells?Prokaryotic cells are single-celled and have cell walls, but eukaryotic cells are multicellular but don't have cell walls.
Which of the following are true similarities between prokaryotic and eukaryotic cells?Eukaryotic and prokaryotic cells both use deoxyribonucleic acid (DNA) as the basis for their genetic information. This genetic material is needed to regulate and inform cell function through the creation of RNA by transcription, followed by the generation of proteins through translation.
