BOT 331 Exam 1 Questions With Solutions
BOT 331 Exam 1 Questions With Solutions There are two types of nucleic acids: DNA and RNA. There is both DNA and RNA inside the nucleus, mitochondria and plastids. Is there both DNA and RNA in the cytosol? Explain your answer No, not both. DNA remains in the nucleus. RNA copies of genes are synthesized in the nucleus, but then moved out pores into the cytosol, where ribosomes (also containing RNA) bind RNA and use the RNA to direct synthesis of proteins. In the case of plastids and mitochondria, RNA copies of the organelle's genes remain in the organelle, and are translated into protein by ribosomes in the plastid stroma or mitochondrial matrix
