Download Dna * Structure, transcription and translation

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?

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?
