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, ...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 mRNA sequences, because several codons can correspond to one amino acid.C. the amoun...

10.6. To trace family relationships between distantly related organisms such as humans, algae, bacteria, and archaea, one should compare their genomes in regions … A. that evolve rapidly. B. that have a higher mutation rate. C. that code for proteins. D. where mutations are hardly tolerated. E. where most mutations are selectively neutral. 10.7. Laboratory strains of the model organism Escherichia coli that are resistant to antibiotics are very often used in research laboratories as we...
