Answer:
The correct answer is : A.
Explanation:
- This is because of the following reasons:
- Escherichia coli is a bacteria and hence is a prokaryote.
- The cloning of human (eukaryote) genes is done to obtain in-vitro protein expression which are to be used a pharmaceutical compounds.
- Although the phenomenon of Central Dogma takes place in both Prokaryotes and Eukaryotes, the mechanism is very different.
- Some of the differences includes:
- Eukaryotic genes contain certain non-protein encoding sequences called the Intron sequences which needs to be removed from the transcribed mature mRNA by Spliceosome. This phenomenon is absent in prokaryotes as they do not possess introns. Hence, proper processing of eukaryotic mRNA is not possible in prokaryotes.
- The mature eukaryotic mRNA has a 5' cap and 3' polyadenylated tail which is added by a capping enzyme and a poly-A polymerase enzyme to increase their stability. This will not be possible in a prokaryote as they lack these enzymes.
- The translation of membrane proteins and secretory proteins is carried on by the ribosomes bound to the endoplasmic reticulum. This structure is absent in prokaryotes, hence they will be unable to produce a proper polypeptide sequence.
- Finally, the eukaryotic proteins undergo various modifications after formation, like methylation, acetylation, etc. These reactions cannot be carried out in a prokaryote as they lack the respective enzymes.
- Hence, we see a properly folded functional eukaryotic protein cannot be produced in a prokaryote.
It is also called a decision lol!
Answer:
peer review
Explanation:
In science, results or findings from an experiment are usually published in journals. However, before they can be published, they have to undergo series of confirmation. One way to do this is to have several other scientists examine the results before finally publishing it. This is called PEER REVIEW.
PEER REVIEW is the process whereby an article that is about to be published in a scholarly journal is reviewed by researchers or scientists from the same field of study as the original scientist in order to ascertain the quality and validity of the result or findings. A peer-reviewed article is deemed to be of a very high quality.
Answer:
Neurons communicate with each other by sending chemicals, called neurotransmitters, across a tiny space, called a synapse, between the axons and dendrites of adjacent neurons.
