BS 111 (Kopachik) Study Guide for DNA Synthesis Define, describe or illustrate the following: Transforming factor Streptococcus smooth and rough phenotype A. Hershey and M. Chase T2 bacteriophage Conservative, semi-conservative, dispersive replication Ultracentrifugation density gradient Initiator Helicase Topoisomerase Single-strand binding protein Primase DNA polymerase III and I Sliding clamp protein Ligase Replication fork and bubble Leading and lagging strand Okazaki fragments Telomere Telomerase Proofreading Mismatch repair Xeroderma pigmentosa Thymine dimer Nucleotide excision repair 1. Why did some biologists believe on theoretical grounds that proteins, not DNA, convey the genetic information? 2. Hershey and Chase were worried the 20 % of the S-labeled material remaining with cells might be part of the T2 phage genetic material. How could they provide further information that this label material, i.e. protein, was not genetic information? 3.
