What is elongated hollow appendage used for DNA transfer to other bacterial cells?
Bacteria with the F plasmid (free or integrated) make pili (singular pilus, sometimes referred to as the sex pilus) to connect with bacteria that do not have the F plasmid to initiate DNA transfer. However, the pili are actually used as a harpoon to reel in the other bacteria so that physical contact between the membranes of the bacteria could be made. DNA is only transferred after the fusion of the cell membranes. It is also a common misconception to think that bacterial conjugation is like 'sex' since it does not involve recombination of genes or cycles of haploidy and diploidy.
What is the process in which a bacterial cell takes in DNA released by a different bacterial cell called?
== == transformation ------------------------------------------------------------------------------------------------------- Transformation is the process in which a bacteria takes in DNA from the environment. Reference: http://en.wikipedia.org/wiki/Transformation_(genetics) By the way, transduction is the process of DNA transfer by the action of a virus (bacteriophages). The other method of DNA exchange between bacteria is called conjugation, which is the transfer of DNA between bacteria by physical contact.
What is the difference between viral and a bacteria infection?
As simple as that a viral infection is caused by a virus and a bacterial infection is caused by a bacteria.
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.
Differences between bacterial cells and yeast cells?
bacteria cell doesn't have a nucleus

What is Conjugation bacteria?
Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or a bridge-like link between two cells. In bacteria, it is a parasexual way of reproduction. It's a horizontal gene transfer process, like transformation and transduction, but it doesn't entail cell-to-cell communication.

What is the difference between bacterial cidal and bacterial static?
Bacterial cidal kills the bacteria, while bacterial static only stops it from growing and reproducing.
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 difference between viral and a bacteria infection?
As simple as that a viral infection is caused by a virus and a bacterial infection is caused by a bacteria.
What allows the bacteria to join together to transfer genes?
pili or pilus is what allows for conjugation between bacteria i.e. genetic transfer.
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.
What is the difference between a bacterial and yeast cell?
Main difference is Bacteria are prokaryotes.Yeasts are eukaryotes.
Differences between bacterial cells and yeast cells?
bacteria cell doesn't have a nucleus
What is the form of sexual reproduction in some bacteria?
Sexual reproduction doesn't exist in bacteria but bacterial conjugation does. DNA transfer between bacterial cells typically involves small pieces of DNA in the form of plasmids or chromosomal fragments. These new fragments can give antibiotic resistance and other genes that are helpful to the bacteria.
What is the difference between a bacterial rIbosome and a eukaryotic ribosome?
Bacteria have 70s ribosomes.Eukariyotes have 80s ribosomes
