Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
After you gathered your research in the experiment to prove if you were correct or not depending on the outcome of said experiment.
Monoclonal antibodies are made by the fusion of cells of the immune system with B lymphocytes and myeloma cells.
<h3>What is Hybridoma technology?</h3>
- It is one of the best technologies that is used to produce the monoclonal antibody.
- In this hybridoma technology the B lymphocytes that are antibody producing are isolated from a source after the immunization with a specific antigen and then are fused with myeloma cell line to form hybrid cells that are also called as hybridoma cell lines.
- The hybridoma cell lines are then cultured in the laboratory with specific antigen and then the monoclonal antibodies are produced.
- This can be done in in-vivo or in-vitro condition.
- This method is preferred over all because the production of antibodies by this method is good as the antibodies produced are of high purity and highly sensitive and specific.
- These cell lines can also be preserved for a long time.
- Hybridoma technology has resulted in production of different varieties of monoclonal antibodies with specificity with specific antigens as the monoclonal antibodies are produced by single parental B cells.

Fro the answer to the question above,
<span>Based on fossil evidence, eukaryotes evolved about <u>2.1 billion</u> years ago</span>.
<span>Approximately the first single-celled Eukaryotes appeared 2.1billion years</span>.
But the multicellular eukaryotes first appeared at 1.5 billion years ago.

Answer:
30 percent
Explanation:
Protein is essential in living organisms. They are the building blocks of life and help in the replacement and repair of work out tissues of the body. There are various sources of protein which are plant sources and animal sources.
Animal sources include land and aquatic animals.Sea Finfish, ocean catches, and fish-farming provide approximately 30
percent of animal protein sources consumed by humans in the world.
