Verified step by step guidance1
Understand the definition of a gene: A gene is a specific sequence of nucleotides in DNA that contains the instructions to make proteins or functional RNA molecules.
Recall that chromosomes are large structures made of DNA and proteins, containing many genes, so genes are not entire chromosomes but parts of them.
Recognize that genes are made of DNA, which is composed of nucleotides, not amino acids; amino acids are the building blocks of proteins, which genes help to produce.
Know that in eukaryotic cells, genes are located primarily in the nucleus within chromosomes, not in the cytoplasm.
Therefore, the accurate description is that genes are segments of DNA that code for proteins or functional RNA molecules.
