What is DNA?
1. DNA is often referred to as a ladder. What pieces of the DNA molecule make up the rungs of the ladder (the steps)?
2. What pieces of the DNA molecule make up the sides of the ladder?
3. What types of bond occurs between the bases in the DNA molecule?
4. What makes up chromosomes? What is Gene?
5. How long does it take 1 cell to copy its genetic information? 6. How does the DNA copy itself so fast? What tricks does it use?
7. Describe how the bonds between base pairs work to hold the DNA strand together
DNA Replication
1. How many genes are in the human genome?
2. What are the differences between mRNA and DNA?
3. Where in the cell does transcription and translation occur? (give both places)
4. Which RNA piece reads the mRNA and how does it do this?
5. What is the start sequence? What amino acid does this code for?
6. What 3 codes tell ribosomal RNA to stop reading and release the protein?
DNA Extraction
1. List three differences between the virtual DNA extraction lab and the banana extraction lab you did last week.
