Correct Answer: Testosterone
Explanation:
Testosterone is the hormone which is associated with aggression.
Correct Answer: AT
Explanation:
The nucleotides that are present in DNA molecule are 4. They are Thymine (T), Guanine (G), Adenine (A) and Cytosine (C).
Here in this Adenine pairs with Thymine (A - T) and Cytosine pairs with Guanine (C - G).
