RW - Ch7 Sec2 – How DNA works
Date ____________
Period ____
Answer the following questions using COMPLETE and SCIENTIFIC sentences...
- remember to write a minimum of four (4) sentences (R.A.C.E.S.)
a) 1st sentence = Restate the questions and then add your Answer
b) 2nd sentence = Cite evidence you choose to support your answer
c) 3rd sentence = Explain HOW your evidence works
d) 4th sentence = Summarize answer -OR- Second piece of evidence
A) When cells make proteins, why do they make a copy of mRNA to send out of the
nucleus to the ribosome? Why don’t they just send a piece of the original DNA, to
make sure there can’t be any mistakes?
B) What is the purpose of substituting Uracil for Thymine, when making mRNA?
C) Carefully explain the process of going from a gene on the DNA, to making a
protein? (Be detailed, but you don’t have to answer like RACES question)
