Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.
They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.
This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
Answer:
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
Explanation:The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
As molten rocks cool gases such as nitrogen water vapor and carbon dioxide are released
Trace fossils represent things that were alive, it could be footprints, or bones.
I think this option fits best:

Answer:
Prokaryotic are organisms that consist of a single prokaryotic cells and Eukaryotic cell are found in plants, animals, fungi and protists.
Explanation:
they are range from 10-100 micrometre in diameter, and their DNA is contained within a membrane-bound nucleus.
