The CRISPR system

Rzqust [24]

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.

How does the carbon cycle deliver energy to organisms?

ohaa [14]

1) Carbon is removed from the air by photosynthesis in plants
2) Feeding, from animals, passes carbon along food chain/web
3) Carbon dioxide is released back into the air by:
-animals & plants respiring
-bacteria/fungi acting as decomposers
-Burning of fossil fuels (combustion)
