How can small changes in DNA lead to big changes in traits?
Understand the Problem
The question is asking how small changes in DNA can lead to variations in traits. It explores the relationship between DNA composition and observable characteristics in living organisms.
Answer
Gene-level mutations affect proteins, altering traits.
Small changes in DNA can lead to big changes in traits because gene-level mutations affect proteins responsible for various characteristics. These changes can alter protein function, leading to different physical traits or variations.
Answer for screen readers
Small changes in DNA can lead to big changes in traits because gene-level mutations affect proteins responsible for various characteristics. These changes can alter protein function, leading to different physical traits or variations.
More Information
These mutations can be small but still cause significant changes. Proteins created by DNA act as building blocks and regulators within organisms, so any alteration in their structure can lead to noticeable phenotypic differences.
Tips
A common mistake is thinking small mutations always cause noticeable changes. Some mutations are silent and do not impact traits.
