Concept explainers
(a)
To determine: A model which explains the functioning of RecBCD enzyme complex at the time of genetic recombination of bacteria.
Introduction: Bacterial cells undergo the process of genetic recombination to exchange their genetic material by different types of pathways. These pathways require RecA protein in different sets in all these pathways for catalyzing strand invasion.
(b)
To determine: The modified model that explains about the co-infection of bacterial cells and mutated bacteria with two different strains of bacteriophage in which genes recombine at a different level of frequencies near their CHI sites.
Introduction: Bacterial cells undergo the process of genetic recombination to exchange their genetic material by different types of pathways. These pathways require RecA protein in different sets in all these pathways for catalyzing strand invasion.

- Part I. Structure-Function Relationships in Genes 1. Consider the "two-line model" of a gene shown below - each line represents one strand of a DNA double helix, and the transcription start site is indicated as +1. Use the two-line models provided when answering the following questions. 3' 5' +1 Assume that you know RNA polymerase will move to the right during transcription. On the diagram above, do the following: • Label "upstream" and "downstream" on this gene • Label where you would find the promoter min I • Draw a box where you would expect to find the TATA box • Draw a third line below the model representing the RNA transcript (label the ends!) • Label one of the DNA strands as the template strand 3' 2. Now, let's try that again! This time assume that you know RNA polymerase will move to the left during transcription. Repeat the same tasks as before on the diagram below: 5' 5' 3' +1 I I 5' 3'arrow_forwardTrue or False. Explain. A) At no time during protein synthesis does an amino acid make direct contact with the mRNA being translated.
