Question

Knowing that the genetic code is universal, scientists use molecular biological methods to insert the human beta-globin gene into bacterial cells, hoping the cells will express it and synthesize functional beta-globin protein. Instead, the protein produced was nonfunctional and is found to contain many fewer amino acids than does beta-globin produced by eukaryotic cells. Explain why.

Answer 1

Answer is given below :

Explanation:

• When the beta-globin gene is inserted into the bacterial chromosome, during insertion, beta-globin forms a stop codon between the coding sequences of beta globin, resulting in a reduced amino peptide. Acid on translation
• Furthermore beta-globins form a tertiary protein complex with alpha-globin, which in addition to the ham-subgroup forms functional hemoglobin.
• Since we only put the beta-globin gene on the bacterium-chromosome that is not enough to make a functional protein, we found a non-functional protein
