A
Chromosome → Genome → DNA → Gene → Nucleotide
B
Genome → Chromosome → Gene → DNA → Nucleotide
C
DNA → Gene → Chromosome → Genome → Nucleotide
D
Gene → Chromosome → Genome → DNA → Nucleotide
Verified step by step guidance1
Step 1: Understand the hierarchy of genetic structures from largest to smallest. The largest structure is the genome, which encompasses all genetic material in an organism.
Step 2: Recognize that the genome is made up of chromosomes, which are long DNA molecules containing many genes.
Step 3: Identify that genes are specific sequences of DNA that code for proteins or functional RNA.
Step 4: Recall that DNA itself is composed of smaller units called nucleotides, which are the basic building blocks.
Step 5: Arrange the structures in order from largest to smallest as: Genome → Chromosome → Gene → DNA → Nucleotide.
