Conjugation passes a trait from one bacterium to another via a small strand of DNA called a plasmid. True or False?

True. Conjugation is the process of transferring genetic material between two bacteria through direct contact. The small strand of DNA that is transferred is called a plasmid.

What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
What is it called when a bacterium uses a virus to transfer it's DNA to another bacterium?
It is called Transduction.
What types of vectors are used to carry DNA from one species into the DNA of another species?
There is a structure called a plasmid which can do this; it is bacterial in origin.
The act of two bacteria joining and exchanging DNA?
It is called bacterial conjugation, this is not sexual reproduction, since no exchange of gamete occurs.
What is a bacterium that needs oxygen?
A bacterium that needs oxygen is called an aerobic bacterium
What is it called when a bacteria uses a virus to transfer its DNA to another bacterium?
conjugation
Exchange of genetic information that occurs from one bacterium to another through a hollow bridge?
The three forms of bacterial DNA exchange are (1) TRANSFORMATION, (2) CONJUGATION and (3) TRANSDUCTION.
What is it called when a bacterium uses a pilus to transfer it DNA?
Conjugation
A ring of DNA found in a bacterium in addition to the bacterium's main chromosome is?
It's called a plasmid. The ring of DNA
What are the filaments called that help some bacteria stick to surfaced and exchange plasmids through conjugation?
Pili are filaments that help bacteria stick to the surface and exchange plasmid through conjugation.
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.
How does plasmid allow for antibiotic resistance?
A plasmid (conjugative plasmid) that has a resistance gene on it, can transfer itself to another bacterial cell (called conjugation) or assist in the transfer of a non-conjugative plasmid that has a resistance gene to another cell (called mobilization). Whichever way it happens, once the plasmid is transfered to the new cell, this cell too may show signs of resistance to the particular antibiotic. This is one of the ways of the speard of resistance amongst bacteria

What are the filaments called that help some bacteria stick to surfaces an exchange through conjugation?
Pili are filaments that help bacteria stick to the surface and exchange plasmid through conjugation.
What are filaments called that help some bacteria stick to surface and exchange plasmids through conjugation?
Pili are filaments that help bacteria stick to the surface and exchange plasmid through conjugation.
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.
When is a plasmid considered a recombinant plasmid?
When the original function of the gene in the plasmid is altered or another gene is inserted in the non- coding region of the plasmid is called the recombinant plasmid.
