- 7. What are the 4 nitrogen bases? 1. 2. 3. 4. 8. What is their purpose? Why does their order matter? Answer in complete sentences. How does this structure allow a DNA molecule to be copied to make another identical molecule? The answer to this question is that the nitrogen bases interact with one another in predictable ways. Pairing between nitrogen bases on opposite strands is always the same. Notice that the pairing that takes place between nitrogen bases is specific in DNA strands. Adenine, a large base, bonds with thymine, a small base. Guanine, a large base, bonds with cytosine, a small base. This specific bonding pattern that happens between the nucleotides is called complementary base pairing. 9. How do the bases pair? How are A and G similar? How are T and C similar?Which of the following does NOT describe DNA as it occurs in Eukaryotic cells. CHOOSE ALL THAT APPLY: 1. nitrogenous bases of opposite strands are paired through covalent bonds 2. base pairs are stacked 3.4 A (0.34 nm) apart 3. the two strands of one double helix are complementary 4. two long polynucleotide chains 5. there are 20 base pairs per each turn of a double helix 6. adenine pairs with thymine of the neighboring nucleotide in a single DNA strand 7. bases face outside of the double helix 8. consecutive nucleotides of a single DNA strand are linked by hydrogen bonds 9. here are A-T and G-C pairs in DNA double helix 10. sugar-phosphate backbone of a single DNA strand is formed by linking deoxyribose units and phosphate groups through phosphodiester bonds 11. the two strands of one helix are antiparallel 12.double helix 13. the larger major groove alternates with the smaller minor groove along the length of the double stranded DNA I tried 2,3,4,9,10,11,12,13 together and got it…Illustrate some steps involved in DNA replication :Suppose the following base sequence was found in a segment of one strand of a DNA molecule: 3’ A-A-T-A-C-C-T-C-C-T-A-A-C-T 5’ What would be the bases in the complementary strand?
