ppt: Download File. Process of DNA Replication 2. Binary Fission • Bacteria reproduce asexually via binary fission • Each daughter cell is an identical copy (or clone) of its parent cell. DNA Replication is “Semi-conservative” • Each 2-stranded daughter molecule is only half new • One original strand was used as a template to make the new strand 7. DNA replication DNA structure suggests an obvious replication mechanism Watson and Crick noted that “specific [base]pairing…immediately suggests a possible copying mechanism for the genetic material” the model suggested that each strand could serve as a template for making a … • DNA polymerases can find and correct errors. 2. One side of DNA molecule is a . DNA replication occurs before mitosis begins and before the first division of meiosis. Process of DNA Replication 3. 8.3 DNA Replication There are many origins of replication in eukaryotic chromosomes. Priming DNA synthesis – Primase synthesizes RNA primers. Process of DNA Replication Uncoil & unzip DNA molecule Enzyme (-ase) breaks weak Hydrogen Bond between bases B. A single strand of DNA serves as a template for a new strand. DNA replication is the process of a DNA molecule making a copy of itself. One side of DNA molecule is a template for making the other side (strand) B. The rules of base pairing direct replication.

DNA Replication •What are the key events of the template model for DNA replication? Proteins carry out the process of replication. RepA helicase “melts” the DNA at the replication fork 3. Basic Facts of DNA Replication. Vocabulary for ppt 2 Transcription and Translation • Genes Chapter 8.4 and 8.5 • DNA • RNA • Protein • mRNA • tRNA • rRNA • Transcription • RNA Polymerase • RNA bases • Exon • Intron • Amino Acid • Ribosome • Translation • Codon • Anticodon • Genetic Code Chart • Start codon • Stop Codons DNA serves only as a template. (From: AN INTRODUCTION TO GENETIC ANALYSIS 6/E BY Griffiths, Miller, Suzuki, Leontin, Gelbart 1996 by W. H. Freeman and Company. Watson and Crick proposed that one strand serves as a pattern on which another strand is built and this was later proved to be true. Microbial evolution 101. 34.2: DNA Replication is Highly Coordinated An Origin for DNA Replication A helicase • Replication involves initiation, elongation, and termination. Fundamentals: Nucleic acids, DNA replication, transcription, translation and application to molecular detection. –helicase unwinds the double helix –the two exposed strands of DNA act as a template for DNA replication –DNA polymerase adds the correct complimentary base pairs to the exposed strands DNA is replicated during the S (synthesis) stage of the cell cycle. Each body cell gets a complete set of identical DNA. • DNA replication starts at many points in eukaryotic chromosomes. DNA replication ensures that each daughter cell has an exact copy of the genetic material from the parent cell. E. Steps in DNA replication 1. A. Binding of DnaA to oriC and initial unwinding of the helix 2. template. Enzyme brings in complementary N-bases B. • E. colichromosome is circular, double-stranded DNA (4.6x103 kilobase pairs, >1000 bp/sec) • Replication begins at a unique site (origin) • Proceeds bidirectionally until the two replication complexes meet (termination site) for making the other side (strand)?’s 1-3 DNA: The Master Molecule Video. Replication is fast and accurate. Generation 1 Replication copies the genetic information. DNA Replication Complementary base pairs of the nucelotides in DNA are important because it serves as a basis for making an exact copy of the DNA when a cell is divided. DNA Replication • The copying of DNA is remarkable in its speed and accuracy • Involves unwinding the double helix and synthesizing two new strands.
