Answer:
protect the cell from invading phages
Explanation:
<em>The natural role of the restriction enzymes is to protect the cell from invading phages.</em>
The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.
<u>Once a phage invades a bacterium, the restriction enzyme quickly acts by cutting the phage's DNA into smaller pieces, leading to the destruction of the DNA and hence, the protection of the bacterium cell.</u>

Answer:
The correct option is white.
Explanation:
As the options are not given, the options are found online and are as follows;
(a.) green (b.) white (c.) colonies will not grow (d.) blue (e.) clear
Out of this, white is the true option because in recombinant plasmid lac Z gene is disturbed and cannot produce beta galactosidase enzyme and there is no hydrolysis of x gal and no blue so recombinant plasmid gives white colonies)
The answer would be b. in the nucleus DNA instructions are copied as RNA messages. This is called translation. The RNA then takes that information to the ribosome where it is transcribed into amino acids, which will form a polypeptide chain and create a protein! Hope this helped :)
