Generation 1 • DNA replication starts at many points in eukaryotic chromosomes. Process of DNA Replication 3. E. Steps in DNA replication 1. A single strand of DNA serves as a template for a new strand. ppt: Download File. Microbial evolution 101. Each body cell gets a complete set of identical DNA. Proteins carry out the process of replication. DNA replication is the process of a DNA molecule making a copy of itself. template. 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 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. The rules of base pairing direct replication. 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 … 34.2: DNA Replication is Highly Coordinated An Origin for DNA Replication A helicase • Replication involves initiation, elongation, and termination. DNA replication occurs before mitosis begins and before the first division of meiosis. DNA Replication •What are the key events of the template model for DNA replication? DNA and Replication Notes: File Size: 533 kb: File Type: doc: Download File. Enzyme brings in complementary N-bases B. 8.3 DNA Replication There are many origins of replication in eukaryotic chromosomes. (From: AN INTRODUCTION TO GENETIC ANALYSIS 6/E BY Griffiths, Miller, Suzuki, Leontin, Gelbart 1996 by W. H. Freeman and Company. One side of DNA molecule is a . • 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) A. DNA Replication • The copying of DNA is remarkable in its speed and accuracy • Involves unwinding the double helix and synthesizing two new strands. 2. DNA: The Master Molecule Video. Priming DNA synthesis – Primase synthesizes RNA primers. for making the other side (strand)?’s 1-3 Binding of DnaA to oriC and initial unwinding of the helix 2. Basic Facts of DNA Replication. 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. 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. 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 RepA helicase “melts” the DNA at the replication fork 3. • DNA polymerases can find and correct errors. DNA serves only as a template. DNA replication ensures that each daughter cell has an exact copy of the genetic material from the parent cell. Process of DNA Replication Uncoil & unzip DNA molecule Enzyme (-ase) breaks weak Hydrogen Bond between bases B. Replication is fast and accurate. One side of DNA molecule is a template for making the other side (strand) B. Replication copies the genetic information.

Prokaryotic cell. DNA is replicated during the S (synthesis) stage of the cell cycle. –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 34.2: DNA Replication, transcription dna replication ppt pdf translation and application to molecular.!
