What structures are responsible for the union of the sperm and egg nuclei?Multiple choice question.Tubulin from sperm, centriole from eggCentriole and tubulin from the eggCentriole from sperm, tubulin from eggCentriole and tubulin from the sperm
Solution 1
The correct answer is "Centriole from sperm, tubulin from egg".
Here's a step-by-step explanation:
- Fertilization begins when a sperm comes into contact with an egg.
- The sperm's head penetrates the egg, and the sperm's nucleus is drawn into the egg.
- The centriole, which is a structure in the sperm, helps to organize the microtubules during cell division.
- Tubulin, a protein in the egg, is a major component of these microtubules.
- The microtubules, organized by the centriole and composed of tubulin, help align the sperm and egg nuclei for fusion.
- Therefore, the structures responsible for the union of the sperm and egg nuclei are the centriole from the sperm and the tubulin from the egg.
