Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
What would happen if M RNA were radio actively labeled instead of polypeptides is that instead of one seeing the DNA passing through all the molecular factories you will instead see just messenger RNA taking code and delivering it to Ribosome. This is mainly found in cytoplasm and Endoplasmic recticulums.

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
It’s actually called anaerobic cellular respiration because you’re not using oxygen. For example, when you sprint you can’t breathe very well, so you’re not inhaling as much oxygen you need to make that energy for you to move. Your muscles will go into lactic acid fermentation, and the result of that is energy (ATP) along with lactate (lactic acid), and you will probably start feeling pain as the lactic acids build up.
Hope that helps!
