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
