The restriction enzymes that cut the bacteriophage DNA cannot cut the bacterial chromosomal DNA.
Explain this statement. A. The bacteria can cut the viral DNA at its specific restriction site, but they cannot cut their own DNA since bacterial chromosomal DNA has altogether a different DNA sequence than the viral DNA. B. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme. C. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by

Question

The restriction enzymes that cut the bacteriophage DNA cannot cut the bacterial chromosomal DNA.
Explain this statement. A. The bacteria can cut the viral DNA at its specific restriction site, but they cannot cut their own DNA since bacterial chromosomal DNA has altogether a different DNA sequence than the viral DNA. B. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme. C.

anonymous · Answer

Most restriction enzymes recognize relatively short sequences, so A is not true.  An enzyme with a 6 bp sequence cuts about every 4096 bp, on the average.  B is true.  It's hard to tell about C because the text is truncated.
