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 is B. Thermosphere
Correct me if wrong.
Answer: c. It is the first hominin known to have migrated out of Africa.
Explanation:
The Homo erectus were the ancient humans which are considered to be over first relatives which used to have human like body shape, short arms and long legs relative to their torso. The main unique feature about these humans is that these were the first humans which migrate out of the Africa and they were the first humans who starting cooking of food for the first time.
Cells need mitosis in order to keep the supply of cells suitable for the human body to continue circulating with
