Question

The restriction endonuclease EcoRI specifically cleaves double-stranded DNA at the six-base sequence '5-GAATTC-3'. If EcoRI is applied to a large, complex DNA sample (such as as a whole genome) the result should be

Answer 1

The result should be the restriction enzyme EcoRI cuts the DNA every time it finds the sequence 5-GAATTC-3

Step-by-step explanation:

For example, EcoRI cuts human DNA into approximately 10,000 fragments that can range from 1,000 to 20,000 base pairs. The digestion of DNA by restriction enzymes is very simple. Just place the DNA in contact with the enzyme at an appropriate temperature and the enzyme begins the digestion process. The number of pieces is established by the number of restriction sites recognized by the enzyme.
