Question
The strawberry cells that we use have seven octoploid chromosomes per cell. Determine the total chromosome number per cell. Describe the sequence of steps used in this lab to extract and isolate DNA from strawberry cells. The cell wall of plant cells is rather tough, and must be disrupted during the DNA isolation procedure we used. Describe specifically how the cell walls were disrupted in this procedure. One way that eukaryotic cells differ from prokaryotic cells is by the presence of membrane- bound intracellular organelles, particularly the nuclear membrane. Discuss how detergent used in this procedure facilitates the extraction of the DNA. Nucleic acids form a solid precipitate when placed into cold alcohol. Describe how this property of nucleic acids can be used in the extraction of DNA or RNA.Explanation / Answer
ANSWER:
1) Eight chromosomes per cell
2) initial we have a tendency to stony-broke apart the cell walls by physically squishing the fruit. The chemical (detergent) method stony-broke down the cell walls, cell membranes and nuclear membranes. The fruit mixture was cooled to prevent the DNases discharged from the protoplasm from destroying the cell’s deoxyribonucleic acid. The mixture was filtered to separate the big cell components that aren't required. The deoxyribonucleic acid was then precipitated through chemical means that (the ethanol).
3) once the cell walls are noncontinuous throughout mechanical mashing of the fruit, the detergent within theshampoo disrupts the cell and nuclear membranes of every cell to unleash the deoxyribonucleic acid. It will this by dissolving lipids and proteins that hold the membranes along.
4) The chemical (detergent) method stony-broke down the cell walls, cell membranes and nuclear membranes.
5) deoxyribonucleic acid are often used for the identification of individuals concerned in crimes, to assist confirmparentage of individuals and additionally of plants and animals, and to visualize for genetic defects. as an example, the deoxyribonucleic acid of those kiwi/strawberry fruits are often compared to different samples to work out if one among them has been altered in some fashion, like changes that may be created to create a crop a lot of nutrient. deoxyribonucleic acid from one organism carrying a sequence that codes for a particular attribute may additionally be used for transformation. The section of deoxyribonucleic acid containing this specific sequence are often inserted into a special organism so the altered organism currently features a specific attribute that it didn't antecedently carry.
