Answer:
B) a signal-recognition particle that brings ribosomes to a receptor protein in the ER membrane.
Explanation:
Each synthesized protein has to be targeted to the specific location and transported to that location. There are two possible ways for that transport: post-translational transport or co-translational transport.
• Co-translational transport occurs during the process of translation, and proteins transported this way are proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome), plasma membrane proteins or proteins for the exterior of the cell. They have an amino sequence called a signal peptide which sends them to ER first.
• Proteins that do not have a signal peptide stay in the cytosol so, their transport is after the translation (post-translational).
Answer:
Explanation:
the advantages include:
disease and drought resistant crops that require fewer environmental resources for them to grow
higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops
increased supply of food at a cheaper life and the crops could have a longer shelf life
crops bound to be healthy as they ae not constantly treated by pesticides that could harm people
reduce the use of pesticides that might be a great move for the betterment of the food supply
they reduce the use of toxins that could harm the environment as well as the animals and people
disadvantages
unexpected or harmful genetic changes that could result in humans health being threatened
the process of genetically modifying the crops is quite expensive
due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct
the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow
the crops are modified hence biotech foods may be a threat to the human health
