A. Pituitary gland

B. Thyroid gland

C. Adrenal glands

Q #3: A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?

A. 3' STOGUTCGCU

B. 5' AGCTAGCGT S

C. 3' SUCGAUCICA

D. 3' TCGATCGCA 5'

Answer Explanation

The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

3' TCGATCGCA 5'
