I believe that the answer is B
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.
they are caused by mutation. the best example of it are human blood groups.

Rewrite the sentences:
1. all matter is made up of tiny particles calles atoms and molecules
2. right
3. right
4. compounds are chemically joined together
task 2:
1. i know this is element
2. i know this is compound
3. i know this is mixture
task 3:
In this lesson i have learned that Atoms are in everything and are what makes up most of the stuff on earth. They are tiny molecules that make up me and everything around me. I have also learned that atoms are made up of Elements. Elements are chemical molecules that make up things like the air we breathe. However, when more than one element joins together a compound is formed. Compounds make up more physical things around me such as drinking water and salt for cooking. When many different compounds are joined together a mixture is formed. An example of a mixture can be sand and water.
Explanation:
Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules. Dark reactions make use of these organic energy molecules.
