Question
Chapter 17.1, Problem 2CC
Summary Introduction
To describe:
The experiment of Hershey and Chase and to describe why they used phage.
Introduction:
Bacteriophages are the viruses that infect bacteria. They were discovered by Twort and Herelle in 1915. They are also called bacteria eater. They are made up of proteins that cover their genetic material. They grow and increase their number inside a bacterium. They show both the lytic and the lysogenic cycles.

- Q1. Predict the effects (on translation of coat gene and replicase gene) of the following mutations on phage R17 coat gene and replicase gene translation and explain the logic of your answers: a. An amber mutation (premature stop codon) six codons downstream of the coat gene initiation codon. b. Mutations in the stem loop around the coat gene initiation codon that weakens the base-pairing in the stem loop. c. Mutations in the interior of the replicase gene that cause it to base-pair with the coat gene initiation codon.arrow_forwardCan u please solve this?arrow_forwardHello, i understand the question, but i only need to know which option is right, no need for explanation. thanks in advance.arrow_forward
- Discuss how scientists employ a bacteriophagesite-specific recombination system to generateknockin micearrow_forwardExplain the purpose of the antibiotic resistance gene in this experiment. Why is this genetic trait an important part of the recombinant DNA technology process in the biotechnology industry?arrow_forwardPolymerase Chain Reaction (PCR) was invented by Kary Mullis in 1983. This technique had indeed facilitated research in various areas of molecular biology and genetics. You would like to amplify a particular gene fragment from the yeast genome using Polymerase Chain Reaction (PCR): (i) What is the major enzyme required to kick start this reaction? (ii) Besides the enzymes mentioned in Q2 (a)(), state three (3) other chemicals required for the amplification process to be carried out.arrow_forward

State the restriction site that you can use for this purposeand suggest a screening procedure to indicate successful integration of the gene into thehost genome.arrow_forwardplease helparrow_forward
