What is the intentional alteration or transfer of genetic material called?
The transfer of genetic information is called conjugation. It involves transfer of genetic information from one bacterial cell to another, and requires physical contact between the two bacteria involved.
Is mutant bacteria and transgenic bacteria same?
Transgenic: This kind of bacteria is formed by transfer of genetic material from another bacteria. The transfer may be natural or by genetic techniques. Mutant: This kind of bacteria is also a modified one at genetic level, but not due to transfer of genetic material from other bacteria or organism, but due to genetic changes in the organism itself. This changes may be due to UV rays or ionising radiations, or other mutantion stimulating agents (mutagens)
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.
What is the word for the genetic transfer of material between two bacteria that have direct cell to cell contact?
conjugation
How is bacteria DNA prepared for use in gene transfer?
DNA in bacteria is prepared for use in gene transfer by replicating it. When it is transferred, it is already prepared so that it can begin producing new cells based on the provided genetic material.
What is the difference between horizontal gene transfer and vertical gene transfer?
Horizontal gene transfer involves the transfer of genetic material between different organisms, such as bacteria exchanging genes through processes like transformation, transduction, or conjugation. Vertical gene transfer refers to the transmission of genes from parents to offspring, typically through sexual reproduction in eukaryotic organisms.
What is the meaning of the phrase quantitively transfer the precipitate to the filter paper?
To quantitatively transfer something means to transfer every particle of the material. This is opposed to qualitatively transferring which requires just enough to examine.
Which new phenomenon did Griffith focus on during his work with pneumonia causing bacteria and mice?
transfer of genetic material through transformation
Which new phenomenon did Griffith focus on during his work with pneumonia-causing bacteria and mice?
transfer of genetic material through transformation
What is microbial transfer?
It's movement of genetic material from one microbe to another. For example, two bacteria are incubated together in the lab. The resulting cultured organisms end up with qualities from both bacteria.
Describe the three ways that bacteria can gain genetic diversity?
There are three main forms of horizontal transmission used to spread genes between members of the same or different species: conjugation (bacteria-to-bacteria transfer), transduction (viral-mediated transfer), and transformation (free DNA transfer).
What is it called when a bacterium uses a virus to transfer its other DNA to another bacterium?
In the process of conjugation bacteria transfers its genetic material to an other bacteria by using sex pilli not any virus.
