DNA Replication Worksheet DNA Replication results in two DNA molecules__________________________. each with one new strand and one original strand. DNA replications is said to be semiconservative because? a new double helix contains one old and one new strand. In DNA, guanine always forms hydrogen bonds with what? Cytosine the process of _______ produces a new copy of an organism's genetic information, which is passed on to a new cell replication Wat is the first step in the process of DNA replication? Unzip the DNA Which enzyme is responsible for "unzipping' the DNA double helix? Helicase Which enzyme is responsible for assembling the DNA during replication? DNA polymerase 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 If 15% of a DNA sample is made of of thymine, T, what percentage of the sample is made up of adenine, A? 15% In DNA replication: each new double helix is composed of one old DNA strand and one new DNA strand Which of the following statements about DNA replciation is Not correct? Replication occurs as each base is paired with another exactly like it What does DNA stand for? Deoxyribose Nucleic Acid DNA is a ______________________ Polymer, which means that is made up of many repeating single units called monomers What are monomers? nucleotides The backbone of the DNA molecule is made up of two alternating components, what are these? Deoxyniribose, and phosphate There are four different variations of these monmers (four different bases) what are the names of those bases? Adenine Thymine Cytosine Guanine 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 These two bases are purines. Adenine and Guanine adenine and guanine are comprised of 2 rings The two bases that are pyrimidines are thymine and cytosine thymine and cytosine are made up of 1 ring 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 Where one strand of DNA is complementary to the other strand (opposite/matching) Complementary base pairs The bases are paired by ______________________________ bonds along the axis of molecule.
