Which of the following statements are correct? explain your answers.A. An individual ribosome can make only one type of protein.B. All mRNAs fold into particular three-dimensional structures that are required for their translation. C. the large and small subunits of an individual ribosome always stay together and never exchange partners.D. ribosomes are cytoplasmic organelles that are encapsulated by a single membrane.E. Because the two strands of DNA are complementary, the mRNA of a given gene can be synthesized using either strand as a template.F. An mRNA may contain the sequence ATTGACCCCGGTCAA.G. the amount of a protein present in a cell depends on its rate of synthesis, its catalytic activity, and its rate of degradation.
Let's say there is a protein that needs to be made and then exported out of the cell by exocytosis. Put the order of events in the correct order. Transport by vesicle to the plasma membrane for exocytosis. Process new protein in the rough ER. Transcribe into mRNA in nucleus. Transport by vesicle from the rough ER to the golgi apparatus for further processing, modifying, and sorting. Translate mRNA into protein on a ribosome attached to the rough ER in the cytoplasm.
