How many DNA fragments will be formed by the action of the restriction enzymes below?*1 point1

Which of the following restriction enzymes would recognize and cut the following DNA sequence?-TGGATCCA--ACCTAGGT-ANSWEREcoRIAATTTTAAHindIIIAGCTTCGABamHIGATCCTAGSmaICCCGGGGGGCCC

Felicia would like to cut the following DNA segment that is 1230 base pairs in length. The diagram below shows the location of the cut sites for the restriction enzyme Bgl II, measured in terms of the number of base pairs (bp).Assuming she achieved 100 % efficiency inher Bgl II digestion, Felicia will obtain five DNA fragments from this reaction.What will be the length of Fragment 3? Enter the numeric value only.

4. DNA sequences can be cut into smaller fragments by A. gel electrophoresis B. DNA ligase C. restriction endonucleases D. DNA polymerase

The size of the DNA region specifically recognized by type II restriction enzymes is typically
