Amoeba Sisters DNA Replication Watch the video and answer the questions that go along with the video. Video Recap Watch the video instructions! 6 3 6 sugar phosphate hydrogen bond base 5' to 3' 3' to 5' Video Recap Part 2 Watch the video instructions DNA results in two DNA molecules Each with two new strands Each with two original strands One with two new strands and one with 2 original strands each with one new strand and one original strand In DNA guanine always forms hydrogen bonds with cytosine.The process of replication produces a copy of an organism's genetic information, which is passed on to a new cell.What is the first step in the process of DNA replication? DNA strands are unzippedWhich enzyme is responsible for unzipping the DNA double helix? HelicaseWhich enzyme is responsible for assembling new nucleotides onto DNA strand during replication? DNA PolymeraseDNA replication is important for growth and development of a eukaryote because every cell needs a copy of DNA that is identical and has 46 chromosomes. If 15% of DNA is made up of thymine (T), then what percentage of the DNA sample is made up of adenine (A)? 15 70 30 35 If 20% of DNA is made up of adenine (A) then what percentage of the DNA sample is made up of cytosine (C)? 20 40 60 30 Which of the following statements about DNA replication is not correct? Unwinding of the DNA occurs as hydrogen bonds break. Replication occurs as each base is paired with another exactly like it. The process is known as semiconservative replication because one old strand is conserved in the new DNA copy The enzyme that builds or adds new nucleotides is DNA polymerase Complementary base pairs are held together with hydrogen bonds Scientific Discovery of DNA For the scientists listed below, match their contribution to their name. Rosalind Franklin Looked at DNA x-rays Chargaff A=T; C=G Hershey and Chase Viral genetic material is DNA Griffith Harmless bacteria can become harmful because there is a transforming principle Watson & Crick Built a 3D model of DNA Avery DNA was the transforming principle between the bacteria
