[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
human gene may have intron which bacteria cannot process
|
|
|
amino acid codons for humans and bacteria are different
|
|
|
human protein is formed but degraded by bacteria
|
|
|
all of the above
|
Detailed explanation-1: -So, the correct answer is ‘Human gene may have intron which bacteria cannot process’
Detailed explanation-2: -During transformation, a bacterial cell takes up the plasmid. Afterward, that bacterial cell will contain the genes in that plasmid and can express those genes. One example of a transgenic microorganism is the bacterial strain that produces human insulin. The insulin gene from humans was inserted into a plasmid.
Detailed explanation-3: -A bacterial cell was transformed with a recombinant DNA molecule that was generated using a human gene. However, the transformed cells did not produce the desired protein. Reasons could be human gene may have intron which bacteria cannot process.
Detailed explanation-4: -For transformation with recombinant DNA, the bacterial cells must first be made competent which means increasing the efficiency with which the DNA enters the bacterium.
