Question

which best matches a type of genetic material with its description?
nucleotides form a helical structure that is called a gene.
genes combine to form structures called nucleotides.
chromosomes create genes.
dna is located in the nucleus.

Explanation:

Nucleotides are the building - blocks of DNA. A gene is a segment of DNA, not a helical structure formed by nucleotides alone. Genes are segments of DNA that code for proteins or RNA, and they are located on chromosomes. Chromosomes are made up of DNA and proteins, and genes are parts of chromosomes, not created by them. DNA is the genetic material and is located in the nucleus of eukaryotic cells.

Answer:

DNA is located in the nucleus.
