Question

Bacteria and humans use the same DNA components, and both kinds of cells also perform transcription and translation. Which of the following choices is a potentially significant outcome of this shared mechanism? a Bacteria are able to transcribe and translate human DNA. thus, they could evolve into human's b Bacteria are able to transcribe and translate human DNA. and thus, they potentially could produce human proteins c Bacterial and human proteins are identical in amino acid sequence because the mechanism for producing them is the same d Bacterial and human DNA are identical in sequence because the method for producing them is the same

Explanation / Answer

Bacteria are able to transcribe and translate human DNA and thus they potentially could produce human proteins. But the DNA sequence of bacteria and human are not same. The size of the bacterial genome is much smaller than human. Besides they can not produce protein above 40 kd. Bacteria can not make the protein directly because they don't have splicing mechanism their transcription and translation mechanism is also different. We must clone a C-DNA copy to bacterial gene for its expression.
