Question

Answer

Ligases enzymes are useful in joining of DNA material.

Answer

The Enzymes used to join foreign DNA to plasmid is ligases. The plasmid of bacteria replicate this DNA strands along with other which can be further transferred to target cells.##@

Answer

Ligase
because the word itself means to join...
it joing the phosphate sugar linkage

Answer

Enzymes used to join foreign DNA to plasmid is Ligases.

Explanation:
Plasmids are small, circular DNA molecules found in bacteria and some other organisms. They are often used in genetic engineering to carry and replicate foreign DNA. In order to introduce foreign DNA into a plasmid, a process called DNA ligation is performed. This process involves joining the ends of the foreign DNA molecule to the ends of the plasmid DNA molecule.

Ligases:
Ligases are enzymes that catalyze the joining of two DNA molecules together. They form phosphodiester bonds between the 3' hydroxyl (-OH) group of one nucleotide and the 5' phosphate (-PO4) group of another nucleotide. In the context of plasmid DNA ligation, ligases are used to seal the gaps between the foreign DNA and the plasmid DNA, creating a continuous circular molecule.

Nucleases:
Nucleases are enzymes that break down nucleic acids. They can cut DNA or RNA molecules at specific sites. Nucleases are not used in the process of joining foreign DNA to plasmid DNA.

Endonucleases:
Endonucleases are a type of nuclease that cleave the phosphodiester bonds within a DNA molecule. They can cut the DNA at specific recognition sites, creating fragments. Endonucleases are often used in genetic engineering to create DNA fragments with specific ends that can be ligated to other DNA molecules.

Pectinases:
Pectinases are enzymes that break down pectin, a complex carbohydrate found in plant cell walls. They are not involved in the process of joining foreign DNA to plasmid DNA.

In summary, ligases are the enzymes used to join foreign DNA to plasmid DNA. They catalyze the formation of phosphodiester bonds between the ends of the two DNA molecules, creating a continuous circular molecule.
