Why does static friction have a maximum value

If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves.

Explanation:

The correct answer is D. CAA UGG

Explanation:

According to the rule of base pairing the Adenine make complementary base pairing with thymine and thymine with adenine and guanine and cytosine base pairs with each other in DNA.

In RNA in place of thymine, uracil base pairs with the adenine. Therefore according to this base-pairing rule, the DNA strand GTT ACC will give rise to transcript CAA UGG. So in place of adenine uracil has come.  

Therefore the correct answer to this question is D. D. CAA UGG
