In DNA, which type of bonding occurs between the nucleotide bases? aA - B and C - D bA - C and T - G cA - G and U - T dA - T and G - C

Break Down the Problem

1. Identify the nucleotide bases involved in each option.
2. Determine the type of bonds that occur between these bases.

Relevant Concepts

• In DNA, the nucleotide bases pair through hydrogen bonding.
• The correct pairs of bases are:
  • Adenine (A) with Thymine (T) through 2 hydrogen bonds.
  • Cytosine (C) with Guanine (G) through 3 hydrogen bonds.

Analysis and Detail

• Option a: A - B and C - D

  • This option does not specify valid base pairs and appears invalid.

• Option b: A - C and T - G

  • Invalid pairs; A does not pair with C and T does not pair with G.

• Option c: A - G and U - T

  • Invalid pair for DNA; in DNA, A pairs with T, and G pairs with C. U is not found in DNA.

• Option d: A - T and G - C

  • This is the correct pairing; A pairs with T with 2 hydrogen bonds, and G pairs with C with 3 hydrogen bonds.

Verify and Summarize

Upon review, the only correct pairing of bases within the context of DNA is found in option d.

Final Answer

The type of bonding that occurs between the nucleotide bases in DNA is described in option d: A - T and G - C.
