Does flagella allow bacteria to conjugate?
No, flagella are used for movement, not for conjugation in bacteria. Conjugation involves the transfer of genetic material between bacteria through a pilus, a specialized appendage.
What might be the source if an unexpected bacteria appears on a finished smear even if a clean slide was used?
The unexpected bacteria on a finished smear could be due to contamination during the staining process, improper handling of the samples, or a cross-contamination issue in the laboratory environment. It is important to review the laboratory procedures and quality control measures to identify and address the source of contamination.
During conjugation which what structures does a bacteria form that is used to transfer DNA?
conjugation occurs between two bacterial cells and transfers DNA in the form of plasmids. this is one way to transfer of genetic material - it is not sexual reproduction, The other two ways to transfer genetic material between bacteria are transformation and transduction. In order to be able to perform coagulation (transfer of a plasmid) the bacteria must have an F factor (DNA that codes for the PILI protein, which allows the bacteria to create a bridge through which the bacteria inject the plasmid to another bacteria). Bacteria with F factor is called F+, and without it is called F-. F+ can transfer the plasmid to an F- bacteria.
How do you examine live bacteria microscopically?
To examine live bacteria microscopically, a drop of the bacterial culture is placed on a microscope slide and covered with a coverslip. The slide is then observed under a light microscope at high magnification to see the bacteria in their natural, living state. Additional techniques like phase contrast or dark-field microscopy can also be used to enhance the visibility of the bacteria.
Is bacteria used to make foods helpful or harmful?
Bacteria can be both helpful and harmful when used to make foods. Helpful bacteria are used in processes like fermentation to create products like yogurt, cheese, and sauerkraut. However, harmful bacteria can also contaminate food, leading to foodborne illnesses if not properly handled or cooked.
Why is it necessary to excessively rinse the smear with water in experiment identifying bacteria using gram stain?
smear should be rinsed with distill water so that all the small particles attach to the smear will washed away such as some time the crystals of dye are attached to the smear which give the illusion of microbial cell some time, distill water is used because it is free from other microbial cell and ions which can harm the smear.
What structures does a bacteria form that is used to transfer DNA?
Pilus, plasmid
How do I make a silly sentence with the word smear?
The clown used his coat sleeve to smear the cream pie all over the other clown's face.
What is used to make the cells in the blood smear more easily observable?
Wright's stain
How is bacteria used in food?
Bacteria has been used to make cheese.
Is bacteria used in food?
Bacteria has been used to make cheese.
What does the term smear means in microbiology?
In microbiology, smear refers to the process of spreading a sample (such as bacteria or cells) onto a microscope slide for staining and observation. Smears are used to create a thin, even layer of the specimen for better visualization under the microscope.
What test is used to detect cervical cancer?
A gynecologist can perform a Pap smear to find any abnormal cells. You will need to make an appointment at an Obgyn for this.
What is the material that the loop used in bacterial smear make and why?
the loop is called innoculation loop, it is made up of nickel becase before looping a bacteria it needs to be sterilized in the flame, so nickel having high melting and bioling point and neutral in reactivity therefore it is used.
What is the bacteria used to make yogurt?
Bacteria from the genus Lactobacillus.
Does flagella allow bacteria to conjugate?
No, flagella are used for movement, not for conjugation in bacteria. Conjugation involves the transfer of genetic material between bacteria through a pilus, a specialized appendage.
What bacteria is used to make gouda cheese?
No special bacteria is used. the general Lactic acid bacteria is responsible for making it.
