3. An important feature of restriction enzymes is that each enzyme only recognizes a specific palindrome and cuts the DNA only at that specific sequence of bases. A palindromic sequence can be repeated a number of times on a strand of DNA, and the specific restriction enzyme will cut all those palindromes, no matter what species the DNA comes from.
3A. A linear DNA molecule is represented below. The DNA is represented by one line, although in actuality, DNA has two strands.
If the DNA molecule has two restriction sites, specifically two repeats of a specific palindrome sequence,
A and B, for a specific restriction enzyme,
How many fragments would be produced if the DNA is cut by that enzyme?
Number each fragment.
Which fragment would be the largest?
Which fragment would be the smallest?
The sum of the lengths of DNA fragments 1-3 equal the total original length? True / False
