Question
A segment of DNA that codes for a trait
- Gene
- Centromere
- Chromosome
- Chromatid
Hint:
Gene
The correct answer is: Gene
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.

¶This question is based on genetic information and is explained further:
1. Nucleotides: Nucleotides are the monomeric building blocks of nucleic acid polymers, deoxyribonucleic acid, and ribonucleic acid forms. Nucleotides follow genes.
2. Genes: Genes are DNA regions that instruct cells on making proteins and are the fundamental physical and functional units of heredity. Because chromosomes contain genes, their organization is similar to that of chromosomes.
3. Chromosomes: Chromosomes are threadlike structures inside the nucleus of animal and plant cells, made up of a single molecule of DNA and protein.
4. Nucleus: The nucleus is the command center of the cell, sending instructions to the cell to grow, mature, divide, or die. It also contains the cell's hereditary material, DNA (deoxyribonucleic acid). The nuclear envelope protects the DNA and separates the nucleus from the rest of the cells.
5. Cells: Cells are the basic building blocks of life. Human body is made up of a trillions of cells. They provide structural support to the body, absorb nutrients from food, convert them into energy, and perform specialized functions. In addition, cells can replicate themselves and contain the body's genetic material.
