What is the process by which bacteria take piece's of DNA from their environment?
Conjugation Transformation Transduction (A bacterial cell takes up DNA from its environment One bacterium transfers DNA to another bacterium to which it's physically connected A virus moves DNA from one bacterial cell to another)
When and how bacterial vaginosis reached the us?
Bacterial vaginosis is believed to have reached the US in the early 20th century. The exact time and method of transmission is unknown, but it is thought to have spread through sexual contact and other unknown factors.
What do human cells have in common with bacteria cells?
Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.
What plasmids are and how they are used to get bacteria to synthesize a new protein that they normally do not synthesize?
Plasmids are circles of DNA. These have genes that can be transferred from one bacteria that has it to another. These genes can code for a protein that one cell normally doesn't code for. This done by a process called bacterial conjugation.
What is it called when a bacterium uses a virus to transfer its DNA another bacterium?
Transduction
What is another name for prokaryotic cell?
Another name for prokaryotic cell is a bacterial cell.
How would you define a properly prepared bacterial smear?
A properly prepared bacterial smear involves spreading a thin, even layer of bacterial sample on a clean microscope slide. This is usually achieved by using a sterile loop or swab. The slide is then heat-fixed to kill the bacteria and adhere them to the slide for staining and microscopic examination.
In regards to bacterial growth define colony?
A colony is a visible cluster of bacteria that has grown and divided on a solid agar surface. Each colony arises from a single bacterial cell and represents a genetically identical population of bacteria. Colonies can vary in size, color, shape, and other characteristics depending on the type of bacteria.
What is the process by which bacteria take piece's of DNA from their environment?
Conjugation Transformation Transduction (A bacterial cell takes up DNA from its environment One bacterium transfers DNA to another bacterium to which it's physically connected A virus moves DNA from one bacterial cell to another)
The process by which one strain of bacteria is apparently changed into another strain is called what?
The process by which one strain of bacteria is apparently changed into another strain is called bacterial transformation. This process involves the uptake and expression of foreign DNA by bacteria, leading to genetic changes.
When and how bacterial vaginosis reached the us?
Bacterial vaginosis is believed to have reached the US in the early 20th century. The exact time and method of transmission is unknown, but it is thought to have spread through sexual contact and other unknown factors.
What are the transgenic bacteria?
Transgenic bacteria are bacteria that have been genetically modified to contain genes from another organism. These genes are usually inserted to give the bacteria new functions, such as producing a specific protein or metabolizing a particular substance. Transgenic bacteria are commonly used in biotechnology and research.
Which type of sexual exchange occurs among bacteria in which DNA is carried into a bacterial cell by means of bacteriophage?
Transduction is the type of sexual exchange among bacteria in which DNA is carried into a bacterial cell by means of a bacteriophage virus. The bacteriophage acts as a carrier of genetic material, facilitating the transfer of DNA from one bacterium to another during the infection process.
What do human cells have in common with bacteria cells?
Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.

How can one slow the reproductive process of bacteria?
One way to slow the reproductive process of bacteria is by using antibiotics that target specific mechanisms essential for bacterial growth. Another way is by limiting the availability of nutrients necessary for bacterial replication. Additionally, maintaining good hygiene practices can help prevent the spread of bacteria and minimize their opportunities for reproduction.
What is it called when a bacterium uses a virus to transfer its DNA another bacterium?
