Answer:
yes
Explanation:
prokarotic cells are single celled and can procreate on their own
The correct answers are:
• transcribe RNA that combines with a protein that has a DNA-cleaving function.
• identify viral DNA by complementary base pairing with template DNA.
CRISPR is a DNA sequence found in bacteria (or other prokaryotic cell), derived from DNA fragments from viruses that have previously infected that bacteria. Bacteria use CRISPR to destroy DNA from next similar viruses. So, it is form of antiviral defense in bacteria.
Cas9 is an RNA-guided DNA endonuclease enzyme (DNA-cleaving function) associated with the CRISPR that cleave specific sequences of DNA complementary to the CRISPR sequence.
Explanation:
Advantages :
1}These are the main source of power generation.
2}These projects control the floods because water can be stored in them. These projects have converted many, 'rivers of sorrows' into 'rivers of boon'.
3}These projects are the main source of irrigation and also help in conserving soil.
Disadvantages:
1}Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning, i.e, to produce eggs.
2}It resulted in the displacement of local communities.
3}The multipurpose projects induced earthquakes, caused waterborne diseases.
