Which enzyme do scientists use to bond a new gene to plasmid dna? a. dna polymerase b. dna ligase c. rna polymerase d. restriction endonuclease

DNA ligases are used for bonding a new gene.
In a process of DNA cloning, the gene of interest is inserted into the DNA plasmid of bacteria. Different enzymes are used for different steps of this process. For example, restriction enzymes are enzymes used for cutting the DNA and DNA ligases are used for joining together different DNAs. Such plasmid (with a new piece of DNA) is inserted inside the bacteria in the process called transformation.

Sharks can absorb oxygen through their gills and whales use different organs called lungs to breathe
