Question

what basic unit of heredity is found on segments of dna and are passed on from parent to offspring?
nucleotide
gene
phosphate molecule
deoxyribose sugar

Explanation:

• A nucleotide is a basic building block of DNA, consisting of a sugar, phosphate, and nitrogen - containing base. It is not the unit of heredity.
• A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule. Genes are the basic units of heredity and are passed from parents to offspring.
• A phosphate molecule is part of the DNA backbone (along with deoxyribose sugar). It is not the unit of heredity.
• Deoxyribose sugar is part of the DNA backbone (along with phosphate). It is not the unit of heredity.

Answer:

gene
