In each sugar, one of the four nitrogenous bases is anchored: adenine (A), cytosine (C), guanine (G) or thymine (T). The two strands are held together thanks to the hydrogen bonds between the complementary bases, that is, adenine with thymine, and cytosine with guanine.]]> 2021-05-28 21:36:55 UTC https://padlet.com/tomasrivar/g2546dc623rvz5ck/wish/1569751055 3: Why it’s necessary to smash the strawberries? tomasrivar https://padlet.com/tomasrivar/g2546dc623rvz5ck/wish/1569751448
This causes the cells to open up and the DNA to be released.

Regarding the components present in the extraction solution: the soap helps to dissolve the cell membranes and the salt is added to break the protein chains that join the nucleic acids, releasing the DNA chains.

The DNA molecule consists of two strands that wind together to form a double helix structure. Each chain has a central part made up of sugars (deoxyribose) and phosphate groups.

DNA is made up of basic chemical components called nucleotides. These building blocks include a phosphate group, a sugar group, and one of four types of alternative nitrogenous bases.

NO, because the Strawberries are ideal for doing this experiment for two reasons: they are the fruit with which more DNA is obtained and, in addition, they are octoploid, that is, they have eight identical sets of chromosomes (human cells are diploid, that is, have two sets of chromosomes except for gametes). These circumstances make strawberry DNA easy to extract and see.
