The answer is Heredity! :)
Specialized <span>proteins </span><span>attach to the </span>DNA<span> strand and make a copy of the DNA sequence in the form of a molecule called messenger </span>RNA<span> (mRNA). </span><span>The genetic message is transferred outside the nucleus via mRNA. Hope this answers the question. Have a nice day.</span>
Answer:
The correct answer is b. recognizes foreign DNA sequences that have previously entered the cell and directs the Cas proteins to destroy them.
Explanation:
Clustered regularly interspaced short palindromic repeats (CRISPER) is the sequences of DNA found in the genome of prokaryotes and archaea. These sequences are added at a crisper locus in DNA by bacteria through capturing bacteriophage DNA during infection.
Then this sequence is used to detect a similar sequence of bacteriophage during subsequent infection and destroy them by Cas9 enzyme. Cas 9 enzyme uses a crisper sequence as a template to destroy similar phage DNA.
So the CRISPER Cas system provides an adaptive defense mechanism to bacteria against foreign DNA coming from bacteriophage. Therefore the correct answer is b.
The answer would be florida
