Answer

Genes provide instructions for building proteins, which determine an organism's traits.

Solution

To determine how genes influence an organism's traits, let's analyze each option: A) **By directly controlling all parts of an organism's development**: This statement is misleading. While genes play a significant role in development, they do not control all aspects directly; environmental factors also play a crucial role. B) **By using the environment to determine an organism's characteristics**: This option suggests that genes rely solely on environmental factors, which is not accurate. Genes provide the blueprint, but the environment can influence how these traits are expressed. C) **By randomly selecting traits from a variety of possibilities**: This option implies randomness in trait selection, which does not accurately reflect how genes work. Genes are inherited and follow specific patterns of inheritance. D) **By providing instructions for building proteins that determine an organism's traits**: This statement is correct. Genes encode the information necessary to produce proteins, which are essential for the development and functioning of an organism. Proteins play a critical role in determining traits. Based on this analysis, the correct answer is: **(D) By providing instructions for building proteins that determine an organism's traits.**

The Deep Dive

Genes are like the blueprints of life! They don’t just tell an organism what it will look like; they instruct cells on how to produce proteins, which are the building blocks of all its traits. For instance, the gene responsible for producing melanin will dictate whether a person has dark or light skin. This interaction between genes and proteins ultimately shapes characteristics like eye color, hair texture, and even susceptibility to certain diseases. Not only do genes set the groundwork for traits, but they also engage with the environment to fine-tune them. For example, a plant's growth might be influenced by sunlight, water, and soil quality, showcasing the nature-versus-nurture theme! Interestingly, some traits can appear dominant over others based on varying environmental conditions, showcasing the exciting complexity of heredity and the role these tiny code carriers play in life forms.
