Bio Transcription and Translation

The video shows the transcription factors attach to the DNA strand. The green playdoh represents the activator protein which makes contact with the transcription factors. This contact releases the transcription factors and RNA polymerase starts to transcribe the DNA. The RNA polymerase takes in nucleotides complementary to the DNA strand it unwinds, and makes the RNA strand. The RNA polymerase reaches the termination codon and the RNA is completed.

The video for translation has RNA flowing out of the nucleus. This RNA then is grabbed by the ribosome, and translation occurs. As the RNA goes through the ribosome, tRNA with the complementary anti-codon moves into the A-site. The tRNA moves to the P-site and the amino acid is released, then next tRNA moves to the A-site. The first tRNA moves the E-site and leaves, as the other tRNA takes its spot and adds its amino acid to the first one. This repeats until the RNA strands runs out and the protein breaks away.
