From DNA to RNA Activating What are the complementary base pairs? _A___-__T__ and __C__-__G__ Strategy Complementary Base Strand: _TGCCAGATAAGCTTACCG___ Remember! DNA is held together by special _hydrogen bonds___. These bonds can only form between certain bases called _base pairs___. A can only bond with __T____ C can only bond with ___G___ Fill in the correct Base pairs below A = ___T____, C = ____G_____, G = _____C_____, T =___A_______ Now write the “Complimentary Strand” underneath the following strand of DNA: DNA Strand 1 – A T T G C C T G C T A DNA Compliment – T A A C G G A C G A T REMEMBER!! __Ribosomes__________________ are the site of protein synthesis __Amino Acids___________________ are the building blocks of proteins RNA stands for _Ribonuclease Acid__________________ RNA is made in the _in the nucleus_____________________. RNA is important because DNA cannot leave the __nucleus__________. __RNA____ takes the DNA’s instructions out of the ___nucleus_______. RNA moves into the _cytoplasm______________ of the cell where there is room to make ___proteins (protein synthesis) _____________. Two locations of RNA: a. Nucleus b. Cytoplasm - RNA structure is similar to DNA it is made of __nucelotides____________ because it is a _nucleic acid______. - 3 parts to the nucleotide 1. Ribose Sugar 2. Phosphate 3. Nitrogenous Base (A, U, G, C) - There are 4 nitrogenous bases (HERE IS ONE DIFFERENCE!) 1. A 2. U 3. G 4. C - RNA looks like _half of a DNA_____________ because it only has __one strand______________________ - When it base pairs, A can only bond with __U____ C can only bond with __G____ Here is a strand of DNA. Write the COMPLIMENTARY strand of RNA. DNA Strand– A T T G C C T G C T A RNA Strand – A U U G C C U G C U A 1. mRNA: (messenger RNA)-brings info from the DNA in the nucleus to the cytoplasm 2. rRNA: (ribosomal RNA)- binds to the mRNA and uses the mRNA’s information to assemble the amino acids in the correct order 3. tRNA: (transfer RNA)- transports single amino acids to the ribosome to be assembled into a protein
