Answer:
I think the correct answer is option ( A )
Explanation:
I'm not sure
Atoms overcome the attractive forces between them through vaporization and sublimation. In vaporization, the atoms are from gas to liquid while in sublimation, it is from solid to gas which skips liquid state. Through this, the attractive force of the atoms does not meet in the liquid state because sublimation does not undergo in liquid phase.
Answer:
A) Bacteria cannot carry out RNA splicing to remove introns and so produced a much larger protein.
Explanation:
Human is a eukaryote and has both introns and exons in its genes. Transcription of human genes forms a primary transcript that undergoes post-transcriptional modification.
One of the important even during the post-transcriptional modification is the removal of introns and joining the exons together to make a mature mRNA which in turn serves as the template for protein synthesis.
<em>E. coli</em> is a prokaryote and does not have the enzymatic machinery required for the splicing of introns.
Cloning of a complete human gene into the <em>E. coli</em> cells would not form the respective human protein since the bacterial cells would not be able to splice the introns from the primary transcript.
The answer is an open system
