Which best describes DNA polymerase? Group of answer choices an enzyme that removes the sugar molecule from a nucleotide so that the phosphate groups can be linked together an enzyme involved in DNA replication that binds to DNA and facilitates the formation of a new strand of DNA an enzyme that allows the chromosomes to coil around proteins so that the chromosomes can fit into the nucleus an enzyme that deletes specific regions of DNA an enzyme that breaks DNA down into fragments
Which of the following describes the DNA molecule? A DNA molecule is single-stranded and is composed of phosphate and two nitrogenous bases (thymine and cytosine) that follow complementary base pairing rules T-C. A DNA molecule is double-stranded and is composed of sugar, phosphate, and four nitrogenous bases (adenine, thymine, cytosine, guanine) that follow complementary base pairing rules A-T and C-G. A DNA molecule is single-stranded and is composed of sugar and four nitrogenous bases (adenine, thymine, cytosine, guanine) that follow complementary base pairing rules A-G and C-T. A DNA molecule is double-stranded and is composed of sugar and two nitrogenous bases (adenine, and guanine) that follow complementary base pairing rules A-G.

Frederick Griffith documented bacterial transformation. Which statement is true concerning his experiments? DNA that was not contained within a live cell caused the death of the host organism. DNA from dead Streptococcus cells entered live cells and altered the live cell's characteristics. The two strains of Streptococcus were visually indistinguishable. Heat treatment of the Streptococcus strains destroyed the DNA molecules.
