ACROSS DOWN 2. five-carbon sugar found in DNA nucleotides 1. relationship of two DNA strands to each other 3. enzyme that adds nucleotides to exposed nitrogen bases 4. disease-causing 5. Baserules describe the arrangement of the nitrogen bases between two DNA strands. 4. substance prepared from killed or weakened microorganisms 6. change in phenotype of bacteria caused by the presence of foreign genetic material 7. the process by which DNA is copied 9. A replication is the area that results after the double helix separates during replication. 8. The term double is used to describe the shape of DNA. 10. a virus that infects bacteria 11. enzyme that separates DNA by breaking the hydrogen bonds that link the nitrogen 1 bases 2 12. name for DNA subunit 3 4 5 6 7 8 9 10 11 12 Copyright © by Holt, Rinehart and Winston.

The capsule protects the bacterium from the body’s defense systems and this makes the bacterium virulent. able to cause disease The mice remained healthy. The mice still lived. The mice died. The live R bacteria had acquired polysaccharide capsules. d DOWN 1. COMPLEMENTARY 4. VIRULENT 5. PAIRING 7. REPLICATION 9. FORK SECTION: THE STRUCTURE OF DNA Science Skills 1. A double helix consists of two strands twisted around each other. INTERPRETING DIAGRAMS 2. It provides a visual model of a double 3. 4. 5. 6. 7. 1. A. phosphate group B. pyrimidine (thymine) C. hydrogen bond D. purine (adenine) E. deoxyribose 2. the hydrogen bonds between the helix’s structure. Answers may vary. Possible responses include a coil of fencing material or railroad tracks that wind around a mountain or a coiled telephone cord. Nucleotides are units, or parts, that form DNA. a phosphate group, a five-carbon sugar molecule, and a nitrogen base It stands for deoxyribonucleic acid. a bases; cytosine and guanine form three hydrogen bonds, whereas adenine and thymine form only two hydrogen bonds. 3. TAA-GGC Concept Mapping SECTION: THE REPLICATION OF DNA 1. the process by which a copy of DNA 2. 3. 4. 5. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. is made during the synthesis (S) phase of the cell cycle before a cell divides the double helix must unwind Part a. The two original DNA strands separate or unwind. Part b. DNA polymerases add complimentary nucleotides to each strand. Part c. When both strands are completely copied, all enzymes detach. This process produced DNA molecules, each composed of a new and an original strand. c Watson and Crick Franklin and Wilkins amount of base pairs double helix purine or pyrimidine pyrimidine or purine replication DNA polymerase nitrogen base phosphate group or five-carbon sugar five-carbon sugar or phosphate group Copyright © by Holt, Rinehart and Winston.
