which of the following completes a false statement? two strands of dna:
are joined by complementary base pairs
form part of a single chromosome
are joined by peptide bonds
are anti - parallel
form a double helix

Explanation:

To determine the false statement about DNA strands, we analyze each option:

• "are joined by complementary base pairs": True, as DNA strands pair via A-T, G-C.
• "form part of a single chromosome": True, as chromosomes contain DNA (with two strands in a double helix).
• "are joined by peptide bonds": False, peptide bonds link amino acids in proteins, not DNA strands. DNA strands are linked by hydrogen bonds between base pairs.
• "are anti - parallel": True, DNA strands run in opposite 5' - 3' directions.
• "form a double helix": True, DNA has a double - helix structure.

Answer:

C. are joined by peptide bonds
