1. Describe what the “genetic code” means. What is a codon? Anticodon? Stop codon?
2. How to you take a DNA sequence and deduce a codon/anticodon, template, nontemplate strand?
3. Describe the characteristics of a tRNA. Why are these molecules considered bifunctional?
4. What is the wobble hypothesis? (codon-anticodon interactions)
5. How are amino acids activated?

9. Centrifugal forces resulting from riding a roller coaster can be a challenge to your blood pressure, as blood trends to flow to your legs instead of your carotid arteries and aorta. A similar effect takes place as you wake up every morning. How does your body cope with these sudden changes in blood pressure?

In the absence of oxygen, two different cultures of E. Coli are growing in a minimal medium- both with the same basic composition of standard salts, and both containing ammonium chloride as the nitrogen source, and glucose as the carbon source. Only the first culture contains sodium nitrate in addition.
1) Describe the two metabolic pathways in the two different cultures and put them in to a global perspective. To what nutrients cycles do they contribute, and how?
2) what are some of the major groups of environmental
bacteria that use these pathways? Describe them briefly. What are
typical habits where these pathways play an important
role?

2.A portion of a gene, which is transcribed into RNA, but not translated into protein.
3.A sequence of nucleotides coding for a single gene product that is transcribed into mRNA.
4.The section of DNA to which RNAP first attaches itself to when initiating the transcription of a structural gene.
5.A protein that blocks gene action with an operator site on the DNA.
