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 a function of the pili found on the surface of some bacteria?
There are two types of pili found on some bacteria. Sex pili are used by bacteria to transfer plasmids during conjugation. Common pili (fimbrae) are used to stick to surfaces.
Bacteria usually reproduce asexually However sometimes they do exchange genetic information during conjugation Which structure do they form during this process that is used to exchange genetic info?
Pilus Pilus, Plasmid
Which new phenomenon did Griffith focus on during his work with pneumonia-causing bacteria and mice?
transfer of genetic material through transformation
What is chioromphinacol?
Chloramphenicol is an antibiotic, inhibits the synthesis of proteins in bacteria. Aparently Chloramphenicol interfer during the transfer of amino acids from RNA-bound amino acids to Ribosome
What happens during conjugation in Spirogyra?
a form of sexual reproduction. Spirogyra and its relatives can be found during summer as pond scum, floating mats in ponds.Two filaments of Spirogyra form conjugation tubes. The contents of one cell passes through the tube an fuses with a cell from the other filament.
What does bacteria do in the process of conjugation?
Bacteria exchange genetic material during the process of conjugation to ensure the rise of another offspring which is genetically different.

What is the function of the pili in a prokaryote cell?
Pili are the fine hair like projections present on the bacterial cell surface. Only one or few pili are present on the cell surface. They are genetically determined, and are used for attachment in case of pathogenic bacteria. The sex pili are involved in bacterial conjugation and are found exclusively on the cells that donate DNA during this process.

Which structures within the ear transfer a sound wave during hearing?
The ear drums are responsible from transferring sound waves from the outer ear to the middle ear. It vibrates in response to these waves.

During transformation of bacterial cells chemicals that weaken bacterial membranes or pulses of electricity that temporarily tear tiny holes in the cell are used to?
Helps the bacteria transfer faster
