Calibri Regular (Bo 11 BIU aA or cultivated bananas? (indicate wnetner you used strawberries or pananas) v Strawberries are octaploid, which means they have 8 copies of each type of chromosome inside the nucleus of each cell. Strawberries have 7 chromosomes, so they have a total of 56 chromosomes in every cell. Bananas are triploid, which means they have 3 copies of each type of chromosome inside the nucleus of each cell. Bananas have 11 chromosomes, so they have a total of 33 chromosomes in every cell. 2. Which three components make up a DNA nucleotide? Are any of these components charged (+/-)? Are any polar? Each nucleotide is made up of a nitrogenous base, a pentose sugar (deoxyribose), and a phosphate. !!! 3. Describe the polarity of the two components of a phospholipid. A phospholipid is made of a polar head (which includes the phosphate group and the glycerol molecules) and 2 non-polar fatty acid tails. The head is hydrophilic and the tails are hydrophobic. Phospholipids make up cell membranes and form a bilayer. The polar heads stick out towards the water-based fluids, whereas the non-polar tails face inwards, toward each other. 3. Considering the effect of soap on the oil and water solution in Experiment 1, and soap's effect on greasy dishes, describe the action of the soapy extraction buffer on the cellular and nuclear membranes. Correctly use the following terms: amphipathic, non-polar, polar. Soap break the cell and nuclear membranes resulting in the release of DNA from the cell. hipathic as it contains a polar head and non-polar tail. Similarly, the nuclear The non-polar tail of soap acts on
