What is NOT true of all cells? a. They have membrane transport proteins. b. They synthesize proteins on the ribosome. c. They replicate their genome by DNA polymerization. d. They transcribe their genetic information by RNA polymerization. e. They use RNA as a template for genomic DNA polymerization. 2. Imagine a segment of DNA (within a gene) encoding a certain amount of information in its nucleotide sequence. When this segment is fully transcribed into mRNA and then translated into protein, in general, what happens? a. The protein sequence would carry more information compared to the DNA and mRNA sequences, because its alphabet has 20 letters. b. The prote in sequence would carry less information compared to the DNA and mRNA sequences, because several codons can correspond to one amino acid. c. The amount of information in the mRNA sequence is lower, because the mRNA has been transcribed using only one of the D NA strands as the template. d. The amount of information in the mRNA sequence is higher, because several mRNA molecules can be transcribed from one DNA molecule . 3. Scientists discover more than 10,000 new species of living organisms every year. What is shared between all of these organisms? a. They are made of cells, whose nuclei enclose their DNA. b. They obtain their energy from sunlight. c. They produce and use adenosine triphosphate (ATP). d. Their genome contains at least 1000 genes. 4. What is NOT true of the plasma membrane? a. It is totally impermeable. b. It contains proteins that move materials across the plasma membrane. c. It contains enzymes that catalyze reactions within the cell. d. It is made of molecules that are both hydrophilic and hydrophobic. e. It allows waste materi als to be removed from the cell. 5. What is NOT a source of movement in a cell? a. Random thermal motions b. Gliding in a specific direction without energy input c. Motor proteins moving large assemblies d. Ions moving across a membrane due to ion pumps e. Proteins moving the cell forward 6. Which of the following is NOT a source of movement in a cell? a. Random thermal motions b. Gliding in a specific direction without energy input c. Motor proteins moving large assemblies d. Ions moving across a membrane due to ion pumps e. Proteins mov ing the cell forward 7. Which of the following processes that happens inside of a cell does NOT normally require consumption of free energy by the cell? a. Replication of the genetic material b. Import of nutrients from the environment
