Select the statement(s) that accurately describe the recombinant plasmid shown.
This molecule was made using EcoRI and ligase.
This is a DNA molecule that contains foreign DNA.
It can be taken into a bacterial cell and used to produce foreign proteins.
This is a transformed bacteria.
This is a recombinant endonuclease.
The statements that accurately describe the recombinant plasmid are:
1. This molecule was made using EcoRI and ligase.
2. This is a DNA molecule that contains foreign DNA.
3. It can be taken into a bacterial cell and used to produce foreign proteins.
Explanation:
– EcoRI is a restriction enzyme that cuts DNA at specific sites, allowing foreign DNA to be inserted into plasmids. Ligase is used to join the DNA fragments together.
– A recombinant plasmid is indeed a DNA molecule that contains foreign DNA.
– Once inside a bacterial cell, the plasmid can be replicated and translated to produce foreign proteins.
The other statements, “This is a transformed bacteria” and “This is a recombinant endonuclease,” are not accurate. The first describes the bacterial cell that has taken up the plasmid, rather than the plasmid itself, and the second confuses the concept of plasmids with the enzymes that cut DNA.
