a.

Summary Introduction

To explain: Why an acid-alcohol as a delocorizing agent, when there is an error is made while performing spore staining.

Introduction: Spore staining is a staining technique that is used to differentiate the bacterial endospores from the vegetative cells. Endospores are formed by a few genera of bacteria, for example, Bacillus. Bacteria are able to thrive in extreme conditions by forming spores. Spores are highly resistant to heat, chemicals, desiccation, and radiation.   

b.

Summary Introduction

To explain: If an error is made while performing spore staining, then what are the microscopic observations that differ from those observed when the slides were prepared correctly. For example, safranin is used as the primary stain and malachite green is used as the counterstain.

c.

Summary Introduction

To explain: If an error is made while performing spore staining, then what are the microscopic observations that differ from those observed when the slides were prepared correctly. For example, heat is not applied during the primary stain.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
