Build a DNA molecule using small plastic colored tubes and anchor pieces, replicate it, and use half of the "ladder" to construct messenger RNA (mRNA). Nucleotides of RNA are first produced following step-by-step directions. Transcription in the nucleus, and the movement of the mRNA molecule, is simulated by matching mRNA codons to the transfer RNA (tRNA) and its anti-codons. The amino acids then bond to form a protein molecule. Discover how the information stored in the DNA is expressed as a finished protein by disconnecting the protein chain from the tRNA. The tRNAs from the mRNA show their availability to continue. Contents: instruction manual, 11 sets of color-coded parts, and 11 student worksheets and guides. Lab Aid No. 72. Fisher S19376. This kit was purchased with 2006 Title IIA Funds administered by the Board of Regents, State of Iowa and donated by Clarke College, Dubuque, IA. Two-week loan period. | |
