DNA Replication Worksheet 1. DNA Replication results in two DNA molecules__________________________.: each with one new strand and one original strand. 2. DNA replications is said to be semiconservative because?: a new double helix contains one old and one new strand. 3. In DNA, guanine always forms hydrogen bonds with what?: Cytosine 4. the process of _______ produces a new copy of an organism's genetic information, which is passed on to a new cell: replication 5. Wat is the first step in the process of DNA replication?: Unzip the DNA 6. Which enzyme is responsible for "unzipping' the DNA double helix?: Helicase 7. Which enzyme is responsible for assembling the DNA during replication?: DNA polymerase 8. Why is DNA replication important to the growth and development of a multi-cellular organism?: daughter cells need a complete set of DNA to survive 9. If 15% of a DNA sample is made of of thymine, T, what percentage of the sample is made up of adenine, A?: 15% 10. In DNA replication:: each new double helix is composed of one old DNA strand and one new DNA strand 11. Which of the following statements about DNA replciation is Not correct?: Replication occurs as each base is paired with another exactly like it 12. What does DNA stand for?: Deoxyribose Nucleic Acid 13. DNA is a ______________________: Polymer, which means that is made up of many repeating single units called monomers 14. What are monomers?: nucleotides 15. The backbone of the DNA molecule is made up of two alternating components, what are these?: Deoxyniribose, and phosphate 16. There are four different variations of these monmers (four different bases) what are the names of those bases?: Adenine Thymine Cytosine Guanine 17. These bases are of two different types of molecules: purines and pyrimidines. Purines have_________ring(s) in their structure, and pyrimidines have __________ring(s) in their structure.: double single 18. These two bases are purines.: Adenine and Guanine 19. adenine and guanine: are comprised of 2 rings 20. The two bases that are pyrimidines are: thymine and cytosine 1/2 21. thymine and cytosine: are made up of 1 ring 22. Based on this information, scientists could predict that the base ________ pairs with ________ and the base ________ pairs with _______ in the formation of the DNA molecule.: Adenine Thymine Cytosine Guanine 23. Where one strand of DNA is complementary to the other strand (opposite/matching): Complementary base pairs 24. The bases are paired by ______________________________ bonds along the axis of molecule.: Hydrogen 2/2
