Question

Mention any three major conclusions made by the Watson-Crick experiments concerning DNA.

a) Double Helix Structure: Watson and Crick proposed that DNA has a double helix structure, with two strands coiling around each other.
b) Complementary Base Pairing: They concluded that adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C) through hydrogen bonding.
c) Anti-Parallel Arrangement: The experiments suggested that the two strands of DNA run in opposite directions, creating an anti-parallel arrangement.

Answer 1

Watson and Crick's experiments revealed that DNA has a double helix structure, complementary base pairing, and an anti-parallel arrangement.

Step-by-step explanation:

Watson and Crick made several major conclusions about the structure of DNA:

1. Double helix structure: They proposed that DNA consists of two strands that are twisted around each other to form a right-handed helix.
2. Complementary base pairing: They concluded that adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C) through hydrogen bonding.
3. Anti-parallel arrangement: The experiments suggested that the two strands of DNA run in opposite directions, creating an anti-parallel arrangement.
