Summary Introduction
To construct:
A concept map illustrating relationships among bacteria, viruses,
Concept introduction:
The concept map can be defined as the diagram which depicts the relationship between different concepts. This is particularly used for organizing and structuring knowledge. It is comprised of the information that is represented in circles or boxes and they are interlinked with the labeled arrows.
Meningitis is a type of acute inflammation that mainly occurs in the membrane of the brain and spinal cord. Its symptoms are a stiff neck, rash, vomiting, dislike lights, confusion, seizures, and headache. Bacterial meningitis is more fatal than viral meningitis.

Based on this information, does the luxR regulator sequence make a repressor protein or an activator protein? b) How will binding of this complex affect RNA polymerase? Remember this operon is under positive control. c) AHL is a signal molecule that V. fisheri makes to communicate with neighboring bacterial cells. This molecule can diffuse outside of the cell and into another bacterial cell in close proximity. This type of communication between bacterial cells is known as quorum sensing. If bacterial cell density is low how will this affect the lux operon? What will happen if the density is high?arrow_forward1) Given an mRNA with the following sequence, please translate the codons to a chain of amino acids.

Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes. Incubate both tubes in a 37 C water bath for 5 minutes. Questions: 1) What differences would you expect to see between the…arrow_forward
