Answer:
In the extracellular space
Explanation:
Disulfide bonds are interconnections between chains (or between parts of a chain) formed by the oxidation of cysteine radicals, this reaction is catalyzed by specific enzymes.
Intracellular proteins have no disulfide bonds, which are more common in proteins secreted into the extracellular environment.
Disulfide bonds do not form in the cytoplasm because there are a lot of reducers in the cytoplasm (intracellular environment) , making the disulfide bonds unstable. The reducing environment of cytoplasm causes disulfide bonds (S-S) to return to the form of cysteine groups (-SH).
 
        
             
        
        
        
Answer:
True
Explanation:
DNA ligases are enzymes required for replication, repair, and recombination of DNA molecules. The DNA ligase repairs the break in the DNA molecule by the formation of a phosphodiester bond.  
The bacterial genome consists of a circular DNA molecule, thereby laboratories use these enzymes to create recombinant DNA molecules
