From DNA to RNA

Part 1: RNA vs. DNA

1. What major group of biological macromolecules are DNA and RNA examples of? What is their monomer, building block?

2. What are 3 differences between RNA and DNA?

3. What are the 3 kinds of RNA? Describe each one and explain when/how they are used

Part 2: Transcription

1. What is transcription?

2. Where does transcription occur?

3. What molecules are involved in transcription?

4. Where does the mRNA go after it is made?

6. Below is a “transcription timeline” draw a picture to go with each of the three steps. Use the word descriptions below the timeline to help you!

splits apart

9. Make mRNA copies of the DNA strands below:

Example: DNA Strand: 3’AATTGCGATA5’

mRNA Strand: 5’UUAACGCUAU3’

DNA Strand 1: 5’A T A C G A C A T A G G A A C T A T T T A A G T A3’

mRNA Strand:

DNA Strand 2: 5’A A A G G G C C C G A T A G A A C G T A T A G T A3’

mRNA Strand:

-----------------------

5. DNA strands go back together

4. mRNA leaves nucleus

3. RNA nucleotides form mRNA using DNA as template

2. RNA polymerase splits DNA molecule

1. RNA polymerase binds to DNA
