Unit 7 Notes DNA & RNA DNA stands for: ________________________________________ RNA stands for: ________________________________________ Where does DNA “live”? In the ___________________ Why is DNA so Important? DNA is a nucleic acid that contains the ________________ information used in the development and functioning of all living things and some viruses. DNA is like ______________________, instructions, or a code for making proteins DNA’s codes are converted/changed into messages (mRNA) for ____________________ to read and then make proteins. Proteins do most of the hard work of keeping us ________________. What are the parts of DNA? DNA DNA has 2 strands and is often called ___________ _____________ DNA has this type of sugar: _________________________ Nitrogen Bases: A = __________________ T = __________________ C = __________________ G = __________________ A bonds with _____ How to remember? C bonds with _____ How to remember? What 3 things compose a nucleotide? 1 _______________, 1 _______________________, & 1 ___________________________ Lets Practice: What are the complementary nitrogen bases in this sequence of DNA? ATT ____ CGT ____ TAT ____ CGT ____ CTG ____ AAA ____ ACG ____ Why is mRNA Important? DNA is too _________ and CAN’T leave the nucleus…it must send messages mRNA is created by ______ in the nucleus mRNA contains the messages from the DNA and are sent to ____________________ for them to read the instructions for making proteins RNA What are the parts of RNA? * How many strands does RNA have? ________ Which base does RNA not have? _____________________ RNA is Made of: Ribose (_______________) Phosphate (same as DNA) Nitrogen Bases (A,_____, C, G) RNA Nitrogen Base Bonds: U stands for ______________…a different nitrogen base A bonds with ______ (NOT thymine) C bonds with ______ How does DNA tell the cell to make a specific kind of protein? There are 2 major steps in this process * First: ______________ * Second: ______________ Transcription : Process in which mRNA is synthesized (made) from the DNA template. HINT *** Transcription is when _________ is made from ________.*** mRNA: (messenger RNA) holds the recipe for making ________________ SHORTENED CODE = ________ Lets Practice: Create a RNA strand using this sequence of DNA? ATT CGT ___ ___ TAT ___ CGT ___ CTG AAA ACG ___ ___ ___ Lets Practice This Again: Create a RNA strand using this sequence of DNA? ACA CGA TTA CGG ATA CGC ATC ___ ___ ___ ___ ___ ___ ___ Now What?...Translation! Translation: Process in which mRNA attaches to the __________________ and a protein is assembled/made. Codon: 3 base code in DNA or RNA Write 4 examples of codons: ______________________________ Amino Acid: Compounds joined by peptide bonds to build ______________ ***Different combination of Amino Acids make different kinds of proteins.*** tRNA: (transfer RNA) Type of RNA that transports amino acids to the __________________ Anticodon: Nitrogen bases that can pair that corresponds with the codons on the __________ Translation Video: 1. A special region of the transfer RNA, called an _______________, matches up with the genetic word or codon of mRNA. 2. One by one the rest of the amino acids are added to the growing ________________ chain. 3. The RNA message has been successfully ___________________ into protein This goes in your comp book….cut out on black line….label!!! Translation
