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.
I believe it's D don't take my word for it.
Explanation:
the last option is the correct answer
Should be prophase because chromatin coils up, becoming shorter and thicker, thick enough to become visible when stained.
