Scientists discover more than ten thousand 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. E. All of the above. 2.2. All cells … A. have membrane transport proteins. B. synthesize proteins on the ribosome. C. replicate their genome by DNA polymerization. D. transcribe their genetic information by RNA polymerization. E. All of the above. 7.3. Imagine a segment of DNA (within a gene) encoding a certain amount of information in its nucleotide sequence. When this segment is fully transcribed intomRNA and then translated into protein, in general, … A. the protein sequence would carry more information compared to the DNA and mRNAsequences, because its alphabet has 20 letters. B. the protein sequence would carry less information compared to the DNA and mRNAsequences, because several codons can correspond to one amino acid. C. the amount of information in the mRNA sequence is lower, because the mRNA hasbeen transcribed using only one of the DNA strands as the template. D. the amount of information in the mRNA sequence is higher, because several mRNAmolecules can be transcribed from one DNA molecule. 8.4. Which of the following processes that happens inside 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 C. Diffusion of small molecules within the cell D. Regulation of gene expression E. Synthesis of enzymes that catalyze cellular reactions 9.5. Which of the following would you NOT expect to find in a bacterial cell? A. Swimming using flagella
