1 Review Describe the three main difference between RNA and DNA Explain List the three main types of RNA and explain what they doInfer Why is it important for a single genes to be able to produce hundreds or thousands of RNA molecules
11 Transfer RNATransfers each amino acid to the ribosome according to mRNA.
12 TranscriptionSegments of DNA serve as templates to produce complementary RNA moleculesMakes a copyOccurs in nucleus of eukaryotes.
13 RNA polymerase Enzyme similar to DNA polymerase Binds to DNA and separate strandsUses one strand of DNA as a template and makes a complementary RNA strand.
14 Promoters Regions of DNA that have specific base sequences Shows RNA polymerase where to bind and startSimilar signal shows where to stop.
15 RNA Editing Exon Intron The part of the DNA that codes for the protein that is to be madeIntronThe part of the DNA that does NOT code for the protein that is to be made.
16 Why Have Introns Genes and Protein instructions may overlap in DNA Instructions for one protein may cut out one set of introns, but different introns may be cut out for a different proteinDon’t have a complete answerNeapolitan ice cream.
