How can a fusion protein be formed?
A. by removing a portion of the gene, forming a shorter gene and therefore a shorter protein B. by site-directed mutagenesis, where a fragment is replaced with a synthetic sequence containing the altered DNA sequence C. by ligating together the sequences of two different genes, creating a new hybrid gene.
