DNA fragments are cut out restriction enzymes (restriction endonucleases) and then joined together using enzymes called DNA ligases.
<span>Restriction enzymes are enzymes which recognize target sequences (recognition sites) and cuts DNA at or near those sequences.</span>

Explanation: Hope this helps! ^^
I can't draw very well. but, essentially the shape of DNA is a double helix and A pairs with T and T pairs with A. C pairs with G and G pairs with C. No matter what in DNA. What one side has the other side has. The other will always have the match to it on the other side
A= adenine
T=thymine
C=Cytosine
G=guanine
