A: No impact
B: It will change all amino acid sequences of the protein downstream of the insertion point
C: Depending on the insertion point, it may have different effects on the protein
D: An amino acid will be inserted into the protein sequence
E: Three amino acids will be inserted into the protein sequence
A: No impact
B: It will change all amino acid sequences of the protein downstream of the insertion point

D: An amino acid will be inserted into the protein sequence
E: Three amino acids will be inserted into the protein sequence
举一反三
- One can predict the amino acid sequence of a protein from the nucleotide sequence of its gene.
- The ___________________ of a protein is its unique sequence of amino acids.
- The primary structure of a protein is the sequence of amino acids.（）
- Amino acid sequence of the encoded protein is not changed in A: Silent mutation B: Acceptable mis-sense mutation C: Both (A) and (B) D: None of these
- More than ___ of all well-studied proteins contain a single structural domain. The members of these single-domain families can have different amino acid sequences but fold into a protein with a similar shape.
