If the proteins making up a gene were changed or mutated, what impact would this likely have on an organism?(1 point)
A trait of the organism may be changed only in a negative way.
There would be no change as the proteins do not impact traits.
A trait of the organism may be changed in either a negative, positive, or neutral way.
A trait of the organism may be changed only in a positive way.
A trait of the organism may be changed in either a negative, positive, or neutral way.
To answer the questions, let's break down each option and find the correct one.
1. What is a gene?
To answer this question, we need to understand what a gene is. A gene is a section of DNA that encodes a specific protein. So, the correct option is: a section of DNA that encodes a specific protein.
2. Which structure carries genetic information?
To determine the structure that carries genetic information, we need to know where genetic information is stored. In organisms, genetic information is stored in the nucleus. Therefore, the correct option is: nucleus.
3. Which option contains all of the other options listed?
To identify the option that contains all the other options listed, we need to determine the structure that encompasses them. In this case, a chromosome is the structure that contains genes, carries genetic information, and has a centromere. So, the correct option is: chromosome.
4. If the proteins making up a gene were changed or mutated, what impact would this likely have on an organism?
To determine the impact of changing or mutating the proteins making up a gene, we need to consider how proteins function in organisms. Proteins play crucial roles in the functioning of an organism and traits are often determined by the proteins encoded by genes. Mutations in proteins can have various impacts, including negative, positive, or neutral changes to an organism's traits. So, the correct option is: A trait of the organism may be changed in either a negative, positive, or neutral way.
By evaluating the options and understanding the concepts, we can determine the correct answer to each question.
