What is an extrachromosomal piece of bacterial DNA that contains genes not essential for cell growth?
A Plasmid
Bacterial cells which have been transformed with a plasmid are allowed to grow so that they the plasmids everytime they divide?
The transformed bacterial cells will replicate the plasmid along with their own genomic DNA each time they divide. This allows for amplification of the plasmid within the bacterial population. The plasmid can carry genes for antibiotic resistance, gene expression, or other functions that can be advantageous for the bacteria in certain conditions.
What is the bacterial cell called when the f factor is in plasmid form?
When the F factor is in plasmid form within a bacterial cell, the cell is referred to as an F-positive or F+ cell. This means the cell carries the plasmid containing the F factor, which enables the cell to transfer genetic material during conjugation.
What is a multicopy plasmid?
Every plasmid has a copy number that reflects the average number of copies of a certain plasmid inside a host cell(usually a bacterial cell). So a multicopy plasmid, exist in multiple copies in any given bacteria. It is believed that the higher the copy number is, the more efficient the plasmid is at replicating itself.
How does a human insulin genes become part of a plasmid?
1. Scientists remove plasmids, small rings of DNA, from bacterial cells. 2. An enzyme cuts open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome. 3. The human insulin gene attaches the open ends of the plasmid to form a closed ring. 4. Some bacterial cells take up the plasmids that have the insulin gene. 5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.

In genetic engineering what takes up plasmid?
In genetic engineering, the bacterial cell takes up the plasmid
A bacterial cell that has taken up plasmid DNA is?
called a transformed bacterial cell. The plasmid DNA can confer specific traits to the bacterial cell, such as antibiotic resistance, ability to produce certain proteins or enzymes, or other desired characteristics. This process is commonly used in genetic engineering and biotechnology research.

In the process of human gene cloning using recombinant plasmids what is the bacterial plasmid?
The bacterial plasmid is a small circular DNA molecule that is used as a vector to carry the gene of interest in gene cloning experiments. It is introduced into bacteria, where it replicates independently from the bacterial chromosome. The gene of interest is inserted into the plasmid using restriction enzymes and ligase.
How many plasmids in a bacterial cell?
A bacterial cell can contain multiple copies of the same plasmid or different types of plasmids, which can range from zero to many copies depending on the specific species and growth conditions of the bacteria. The number of plasmids in a bacterial cell can vary and is not fixed.
What is the difference between a plasmid and a nucleoid in terms of their functions within a bacterial cell?
A plasmid is a small, circular piece of DNA that can replicate independently from the bacterial chromosome and often carries extra genes that provide advantages to the cell, such as antibiotic resistance. On the other hand, a nucleoid is the region within a bacterial cell where the main chromosome is located, containing the essential genetic information for the cell's survival and reproduction. In summary, plasmids provide additional genetic material for bacterial cells, while the nucleoid contains the core genetic information necessary for cell function.
What is the function of a plasmid in a bacterial cell?
A plasmid in a bacterial cell serves as a small, circular piece of DNA that can carry extra genes, providing the cell with additional functions such as antibiotic resistance or the ability to produce certain proteins.
How is it possible to splice foreign DNA into a plasmid without altering the bacteria's ability to function normally?
A plasmid is an extra-chromosomal element. Strictly speaking, it is not a part of the bacterial mail genome. Plasmids, when first discovered in bacteria, were observed to contain genes that confer special features to the bacteria (like drug resistance). Also, a plasmid is capable of autonomous replication, which means it has its own origin of replication and does not have to wait for the bacterial genome to be replicated. When a foreign gene is inserted into a plasmid, the plasmid has to be transformed into the bacteria. Once transformed, the cDNA in the plasmid is able to replicate every time the plasmid replicated. This does not have any affect on the normal functioning of the bacteria. The organism is merely being used to make copes of the foreign gene and/or harvest an important protein product.
What is a multicopy plasmid?
Every plasmid has a copy number that reflects the average number of copies of a certain plasmid inside a host cell(usually a bacterial cell). So a multicopy plasmid, exist in multiple copies in any given bacteria. It is believed that the higher the copy number is, the more efficient the plasmid is at replicating itself.
