Transcript
Warm-up ■ Receive instructions from me on how to weigh gummy bears ■ Record gummy bear data on sheet ■ Finish your conclusion paragraph and be sure to explain what and how osmosis influenced this experiment. ■ Warm-up question – How do the gummy bears relate to human cells? How does this information come into place in healthcare? DNA – STRUCTURE, TRANSCRIPTION AND TRANSLATION ■ https://www.youtube.com/watch?v=V9BZ3zx8b8I CENTRAL DOGMA OF BIOLOGY DNA DNA ■ Deoxyribonucleic Acid is a double-helixed molecule ■ Shape discovered using xray crystallography ■ Credit for the discovery is given to– James Watson and Francis Crick Rosalind Franklin ■ https://www.youtube.com/watch?v=35FwmiPE9tI DNA CONSISTS OF 4 NUCLEOTIDES A always bonds with T G always bonds with C ■ http://www.geek.com/science/beautiful-dna-explainer-video-does-watson-and-crickproud-1543000/ WORKSHEET 1 TRANSCRIPTION RNA ■ Single stranded ■ Small enough to leave the nucleus ■ Adenine gets paired with Uracil Worksheet 2 TRANSLATION ■ mRNA sections are “read” and matched by tRNA that carry amino acids. These amino acids form chains called proteins. WORKSHEET 3 EXIT TICKET ■ DNA is often called the genetic blueprint. What is it a blueprint for? How does a twisted chain of chemicals create us, or any other living thing?
