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:

• DNA is indeed found in chromosomes. Chromosomes are structures within the cell nucleus that contain DNA.
• Chromosomes are located in the nucleus of a eukaryotic cell.
• Genes are segments of DNA. DNA is made up of nucleotides. But genes are not located within a single nucleotide. A nucleotide is a building - block of DNA (consisting of a sugar, phosphate, and nitrogen - base). Genes are long sequences of nucleotides.
• In the DNA double - helix (often visualized as a ladder), the nitrogen - bases form the "rungs" in the center, paired with complementary bases (A - T and G - C).

Answer:

Genes are located in a nucleotide.
