Strawberry Lab
The lab was done to show how large DNA actually is. One thing I learned in this lab was that DNA, when uncoiled, can span three feet long.
Answer to the question about strawberries being triploids.
A diploid is an organism that has two sets of chromosomes. The organism has one set from the mother and one from the father. A triploid is an organism that has three sets of chromosomes. Most plants tend to be triploids (estimated 30-80%). Triploids have more chromosomes than diploids do, as there are three sets of the chromosomes. A triploid is easier to extract DNA from, because there is most likely more of it. With three sets of chromosomes instead of two, chances are there is more DNA. This means that because the strawberry had more DNA per cell than an average diploid, the strawberry has more DNA to extract which eases the process of DNA extraction.
DNA Inquiry and Research
1.DNA is the genetic code that determines the attributes of all living creatures. It is the building blocks of life. It is deoxyribonucleic acid.
2. Yes, RNA is a type of genetic material. All living creatures possess RNA. This is a different type if genetic material that is needed in all life.
3. There are four bases in DNA
Two dna stands form a helix spiral winding around in a right handed spiral
At and gc are the types of pairings that can match up to bond. A can only bond to c and likewise for g and c.
DNA is present in all living creatures.
There is a phosphate backbone that surrounds the double helix structure.
When DNA splits and reproduces, one strand will split off from the other with all of the links from the middle.
DNA cannot give the full instructions to make proteins without RNA.
4. No, this is not true because all DNA molecules have double helix spirals and are close to the same size. They make up chromosomes, but individually are the same size.
5. The building blocks of the molecule DNA are other molecules called Adenine, Thymine, Guanine, and Cytosine. These building blocks are molecules that interlock to make the double helix connect together in the middle. DNA is also made of other molecules on the edges, but all of the molecules that make it up are made of smaller molecules and individual atoms.
6. It shows that all life is made up of basic elements arranged in a certain way. LUCA tells us that all life started with the same elements in one common organism. From this organism all life comes meaning that the building blocks of DNA should be traceable all the way back to LUCA if possible to preserve remains for these extensive periods of time.
