How do Euglena reproduce?
Euglena reproduce asexually through binary fission, dividing longitudinally.
Where are Euglena found?
Euglena are found in freshwater, saltwater, marshes, and moist soil.
What is Euglena?
Euglena are unicellular microorganisms classified under euglenoids, exhibiting both plant and animal characteristics.
What are selectable markers in plasmids?
Selectable markers are genes, such as antibiotic resistance genes, that allow researchers to identify cells that have taken up the plasmid.
Why are plasmids important in biotechnology?
Plasmids are important because they can be easily modified, replicated, and used to transfer genes. This makes them valuable tools in genetic engineering and biotechnology.
What are Ti plasmids?
Ti plasmids are found in the bacterium Agrobacterium tumefaciens. They are used to transfer genes to plants, creating transgenic plants. They contain T-DNA and virulence genes.
What is the role of the origin of replication (ORI) in plasmids?
The ORI is a sequence of DNA where replication begins, allowing the plasmid to replicate independently within the host cell.
What is a recombinant plasmid?
A recombinant plasmid is a plasmid into which a foreign DNA fragment has been inserted. This allows for the replication and expression of the foreign gene in the host cell.
How are plasmids used in genetic engineering?
Plasmids are used as vectors to transfer and clone genes. They can be modified to carry specific genes, which are then introduced into host cells for replication and expression.
What is the main function of plasmids?
The main function of plasmids is to carry genes that can provide advantages such as antibiotic resistance. They are also used as cloning vectors in genetic engineering.
