Question

a student is creating a computer model to show the result of a change in the structure of a gene. what process occurs from a change in the structure of a gene? place the steps of the model in the correct order. step 1 step 2 step 3 step 4 a different trait may be observed. a different protein may be produced. dna codes for a different amino acid sequence. a nucleotide base on the dna strand is changed.

Explanation:

Step1: Start with gene - level change

A nucleotide base on the DNA strand is changed.

Step2: Impact on amino - acid coding

DNA codes for a different amino acid sequence.

Step3: Protein - level change

A different protein may be produced.

Step4: Observable trait change

A different trait may be observed.

Answer:

Step 1: A nucleotide base on the DNA strand is changed.
Step 2: DNA codes for a different amino acid sequence.
Step 3: A different protein may be produced.
Step 4: A different trait may be observed.
