The information present in the _____ is what determines the characteristics of this human being.
a) Chromosomes
b) DNA
c) Gene
d) Gametes

Options

A. Chromosomes
B. DNA
C. Gene
D. Gametes

Answer

To solve the question, we need to identify which option contains the information that determines the characteristics of a human being. Let's analyze each option step by step:

1. **Chromosomes**:
- Chromosomes are structures within cells that contain DNA. They are made up of tightly coiled DNA and proteins. While they do carry genetic information, they are not the basic unit of that information.

2. **DNA**:
- DNA (Deoxyribonucleic Acid) is the molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms and many viruses. It is the primary carrier of genetic information and determines the characteristics of a human being.

3. **Genes**:
- Genes are segments of DNA that contain the instructions for making proteins, which perform various functions in the body. While genes are important for determining specific traits, they are part of the larger structure of DNA.

4. **Gametes**:
- Gametes are reproductive cells (sperm and egg) that carry genetic information from parents to offspring. They are important for reproduction but do not directly determine the characteristics of an individual.

Based on this analysis, the correct answer is **b) DNA**. DNA contains all the information that determines the characteristics of a human being.
