Life Science Cells Are Us From Genes to Proteins Pre-Test
1. Which of the following matches the organelle to its cellular function? A. Cell membrane - produce usable energy for the cell B. Mitochondria - modifies proteins for export C. Vacuole - break down cellular waste D. Nucleus - store genetic material
2. Tia notices that she has her mothers eyes and her fathers nose. What phenomenon is responsible for this? A. All humans share most of their DNA B. Tia inherited genetic instructions that determine her physical traits from both her mother and father C. Tia and her parents were likely all infected with the same virus D. Both Tia and her parents share the same diet
3. One of the main differences between prokaryotic and eukaryotic cells is that eukaryotic cells have membrane bound organelles whereas prokaryotic cells do not. Which of the following is a structure or compound that both prokaryotes and eukaryotes have in common? A. DNA and RNA B. A nucleus C. Mitochondria D. Rough endoplasmic reticulum
4. In humans, genetic males and genetic females share all the same chromosome pairs except for one. Females have two X chromosomes, and males have an X and Y chromosome. The Y chromosome is much smaller than the X. What can be inferred from this information? A.Genetic females express more genes than genetic males B. The Y chromosome does not do anything C. The Y chromosome contains different genes than the X chromosome that are responsible for male characteristics D. The Y chromosome carries more information than the X chromosome
5. Which of the following best describes the function of nucleic acids? A. Code for protein production B. Provide the main source of energy to the body C. Make up membranes and provide a source of high energy storage D. Facilitate cellular reactions and help the cell maintain homeostasis by controlling the movement of ions
