Question

How would a mutation affect how DNA is eventually read when it forms a protein

Answer 1

Answer:

Explanation:

A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.

Answer 2

Answer:

A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure. The DNA sequence found within a gene controls protein synthesis. If the DNA sequence is altered, this can alter the amino acid sequence within a protein

Explanation:

Your DNA is the blueprint used to make proteins. Your DNA is used to make a strand of mRNA (Messenger RNA.) This is sent to a ribosome where it is read. The codons in the mRNA instruct the ribosome which amino-acid to attach to the end of the protein chain and when to let it go.  

If your DNA mutates then the mRNA copied from it will be different. When that gets to the ribosome the effect depends on just what the altered codon(s) are. The ribosome will blindly follow the instructions it has been given. This might be to add a different amino-acid to the chain or to prematurely release it.
