- REFLECT AND APPLY List three molecular changes that take place in the processing of eukaryotic mRNA.arrow_forwardREFLECT AND APPLY Would you expect mRNA or rRNA to be degraded more quickly in the cell? Why?arrow_forwardREFLECT AND APPLY E. coli incorporates deoxyribonucleotides into DNA at a rate of 250 to 1000 bases per second. Using the higher value, translate this into typing speed in words per minute. (Assume five characters per word, using the typing analogy from Question 36.)arrow_forward
- REFLECT AND APPLY You are studying with a friend who says that the hydrogen-bonded portions of tRNA play no important role in its function. What is your reply?arrow_forwardREFLECT AND APPLY It is possible for the codons for a single amino acid to have the first two bases in common and to differ in the third base. Why is this experimental observation consistent with the concept of wobble?arrow_forwardREFLECT AND APPLY Is the following statement true or false? Why? The flow of genetic information in the cell is always DNARNAprotein.arrow_forward

- REFLECT AND APPLY In prokaryotic protein synthesis, N-formylmethionine (fmet) is the first amino acid incorporated, whereas (normal) methionine is incorporated in eukaryotes. The same codon (AUG) serves both. What prevents methionine from being inserted into the beginning and N-formylmethionine in the interior?arrow_forwardRECALL Are all enzymes proteins?arrow_forwardREFLECT AND APPLY The amino acid hydroxyproline is found in collagen. There is no codon for hydroxyproline. Explain the occurrence of this amino acid in a common protein.arrow_forward
