Question

A recombinase is an enzyme that does all of the following except?

Answer 1

Answer: - ligates DNA strands to one another.

Recombinase is an enzyme that catalyze site specific recombination events within DNA. In meiosis it helps to generate new combination of alleles in the event of crossing over involves genetic recombination. It recognizes specific DNA sequence, mediates cleavage of phosphodiester bonds in DNA, strand exchange between homologous chromosomes, repairs the mismatched DNA bases. It does not ligate DNA strands to one another this is performed by another enzyme named DNA Ligase.

Answer 2

A recombinase is an enzyme that does all of the following except ligates DNA strands to one another.  

Further Explanation:

A recombinase is a type of an enzyme that helps in catalysing the site specific recombination in the DNA. This enzyme mainly acts in multicellular organism such as eukaryotes, virus and bacteria. This enzyme helps in genetic recombination during the process of meiosis and in breaking phosphodiester bond of the DNA.They can easily repair the mismatched problem in the DNA and can easily manipulate the structure of the DNA. Some example of recombinase enzyme is Cre, Hin, Tre, and FLP.

They also help in recognizing the sequence of DNA and in the homologous recombination. A ligase is an enzyme that is responsible for the process of ligation in which the two strands of the DNA are ligate to each other. Thus, recombinase enzyme is not responsible for the process of ligation.
