Textbook Question
Chapter 10, Problem 2PDQ
CONCEPT QUESTION Review the Chapter Concepts list on p. 213. Most center around DNA and RNA and their role of serving as the genetic material. Write a short essay that contrasts these molecules, including a comparison of advantages conferred by their structure that each of them has over the other in serving in this role.

- Okazaki fragments in bacterial cells are 1000–2000 nucleotides in length. Those in eukaryotic cells are much shorter, usually only 100– 200 nucleotides in length. Propose some possible explanations for why Okazaki fragments in bacteria are longer than those in eukaryotes. What difference between the two cell types could lead to the difference in Okazaki fragment length?arrow_forwardtrue or false 1.) The unique stem-loop structures of the transfer RNA helps the RNA perform its function of joining ribosomal proteins to form the sites for protein synthesis. 2.) DNA molecules can perform their function in replication and transcription as long as the 2 strands remain intact and not separated. 3.) Histone proteins are able to associate with DNA segments because of the anionic nature of the amino acids arg and lys. 4.) The long solenoid structure of the chromatin material binds to a protein scaffold and folds further to form the chromatin/chromosome structure. 5.)
