Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.

- <em><u>Nucleolus is a type of cell organelle that is located in the nucleus of an tom. </u></em>Nucleus is the control center of an atom, it controls all the cellular activities taking place in the cell.
- <em><u>Nucleolus is made up of ribosomal RNA and proteins. The main function of the nucleolus is to assemble or formation of ribosomes. </u></em>Ribosomes are cell organelles that are found in the cytoplasm either attached on the endoplasmic reticulum or freely floating in the cytoplasm, where the process of protein synthesis takes place.
Answer: option D.
Phenotype
Explanation:
Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.
Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.
