Lecture 5 (biol3600) dna replication winter 2012 pw
DNA Replication and RNA Production Selent. Replication The process of copying DNA The two chains of nucleotides separate by unwinding and act as templates.
DNA Structure & Replication Chapter 15 continued Bedford County Public Schools – Jami N. Key.
DNA damage and repair Types of damage Direct reversal of damage Excision repair in prokaryotes and eukaryotes base excision nucleotide excision Nonhomologous.
Mutation and Genetic Variation For every gene, there are many different alleles - alleles are versions of the same gene that differ in their DNA base sequence.
Microbial Genetics Lectures John Buchanan Lecture 1 –Mutation (239-248) Types of mutations Detection of mutations –Recombination and Plasmids (285-306)
Mutation. Types and Sources Mutation is a decay force whose ultimate roots are in the second law of thermodynamics (entropy). Living things survive inevitable.
DNA and Genes. The Structure of DNA DNA is a type of nucleic acid DNA is made of subunits called nucleotides Strand of DNA looks like a 3D-double helix.
DNA & DNA Replication. History DNA DNA Comprised of genes In non-dividing cell nucleus as chromatin Protein/DNA complex Chromosomes form during cell division.
DNA: Deoxyribonucleic Acid Biology. Structure of DNA DNA nucleotide has 3 parts: Sugar molecule Deoxyribose Phosphate group Nitrogen-containing base DNA.
Biology 9.3 Replication of DNA Replication of DNA.
DNA Replication in Prokaryotes and Eukaryotes 1.Overall mechanism 2.Roles of Polymerases & other proteins 3.More mechanism: Initiation and Termination.
