12.2 Replication of DNA: Transcript


WHAT YOU WILL LEARN process of DNA making copies role of enzymes in copying DNA leading and lagging strands in DNA replication READING Q s 1LIST the 3 phases of semiconservative replication. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. 20.1 part 2. DNA replication. Earlier on in this unit we learned about mitosis or cell division.. In order for mitosis to occur and chromosomes to duplicate themselves, the DNA must copy itself exactly.. DNA Structure. The discovery of the structure. Francis Crick and James Watson. The deoxyribonucleic acid (DNA) molecule is the genetic blueprint for each cell and ultimately the blueprint that determines every characteristic of a living organism. The DNA molecule was discovered in 1951 by Francis Crick, James Watson, and Maurice Wilkins using X-ray diffraction. . Objectives:. 1. Summarize the roles of the different enzymes involved in replication of DNA.. 2. Explain how the leading and lagging strands are replicated differently . Semiconservative. Replication. Semiconservative vs. Conservative. DNA Polymerase. RNA Primase. Okazaki Fragments. Replication Errors. TeachWithFergy . Preview File. . Please . enjoy this preview of your Power Point. . Some slides appear blank because they have been removed.. DNA REPLICATION. DNA IS COPIED. 1. DURING . S-phase. of . INTERPHASE. PREPARATION FOR CELL DIVISION. SEPARATION. 2. THE . STrAND. OF DNA IS . UNZIPPED. BY . HELICASE. 3. THE POINT OF SEPARATION IS CALLED THE . Dr. Kevin Ahern. Structure. Structure. Structure. One Strand of DNA. Structure. Introduction. Structure. Introduction. DNA Structure. DNA Forms. Semi-Conservative Replication. Discontinuous. Replication. . §. 4.3a DNA Replisome. . §. 4.3b DNA Damage. §. 4.3c DNA . Repair. IV. NUCLEAR BIOCHEMISTRY. §. 4.3a . DNA Replisome. Synopsis . 4.3a. DNA replication involves making . copies or “. replicas” of DNA. BIO…. LIFE….. THINK ABOUT THIS: . What do we do in our lifetime?. What are the major stages of our life?. What are the Major stages of physical development in our lives?. What would it look like. Need to Book. Speakers. A4 paper (coloured). Pair of Compass & Pencils. Split pins. Scissors. Repro. Meselson. and . Stalh. hand out. Describe semi-conservative DNA replication. Learning Objective. By. Dr. R. C. . Nath. ; Associate Professor. Department of Zoology. Govt. Degree College, DMR. .. Structure of a DNA molecule. `. It . has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material. 9.1 DNA Replication is Semiconservative. DNA Replication is Semiconservative. DNA Replication is Semiconservative. Chapter 9: DNA Replication . 9.2 DNA Replication in Prokaryotes. Prokaryotic DNA is circular. Directions: Front of card write term. On back write definition and draw picture . Chromosomes. Thread-like structure made of coiled DNA. Gene. Segment of DNA that codes for a specific trait. Nucleotide. preserve genetic information.. transfer genetic information to new cells as the strands of DNA are copied.. DNA Replication. In . DNA replication. ,. the strands in the original or parent DNA molecule separate to allow the synthesis of complementary DNA strands..
