Question

which of the following incorrectly matches the term with its location?
○ dna is found in a chromosome.
○ chromosomes are found in the nucleus of a cell.
○ genes are located in a nucleotide.
○ nitrogen bases are located in the central rungs of a dna ladder.

Explanation:

To determine the incorrect match, we analyze each option:

• DNA is indeed found in chromosomes (chromosomes are made of DNA and protein), so this is correct.
• Chromosomes are located in the cell nucleus (in eukaryotic cells), so this is correct.
• Genes are segments of DNA, and nucleotides are the building blocks of DNA. Genes are not located in nucleotides; instead, nucleotides make up DNA, which contains genes. This is incorrect.
• Nitrogen bases form the rungs of the DNA double - helix (the "ladder" structure), so this is correct.

Answer:

C. Genes are located in a nucleotide.
