All living organisms (plants, animals, and bacteria) are made up of cells. Any cell consists of many parts but the parts that play the key roles are the nucleus, cell membrane, and cytoplasm. The nucleus is like the “brain” of the cell (that also contains DNA). The cell membrane is like a wall that guards the cell. And the cytoplasm is a jelly-like substance which contains other smaller organelles like mitochondria that generates energy for the cell. Purpose/Investigation Question
For this lab we are asked to obtain the DNA of kiwi. I think we are doing this to get a picture of how scientists observe certain aspects of organisms by extracting DNA. For example, scientists can identity genetic disorders and perhaps even find cures by experimenting with the DNA. I also think that the purpose of this experiment is to have a better picture of the appearance of DNA in comparison to the pictures we see in our textbooks.
Deoxyribonucleic acid which is usually abbreviated as DNA is a molecule that is found in any living cell of an organism. DNA has instructions for the cell. This molecule exists inside of the nucleus in a cell. The DNA molecule consists of four nitrogen bases called, adenine, thymine, guanine, and cytosine. The nitrogen bases lead to the formation of the rungs of the DNA ladder. DNA plays a key role in the formation, growth, and reproduction in any organism and cells. The picture below will illustrate the appearance of DNA:
In addition to everything, doing this DNA kiwi extraction shows how simple it may be to extract DNA from a living organism which is very essential because DNA gives important information about a certain living organism. The investigation question for this lab is: How to obtain the DNA of kiwi and how it works? Hypothesis
If I mash the kiwi fruit so that the surface area is big and some cells may break and add another mixture to...
