Each statement describes a type of gene regulation. Determine if it describes regulation at the transcription, translation or post-translation level.

1. Genetic regulatory proteins bind to the DNA. Transcription / Posttranslation / Translation
2. A transcription terminator forms in the RNA. Transcription / Translation / Posttranslation
3. Repressor proteins bind to an mRNA and prevent ribosome binding.Translation / Posttranslation / Transcription
4. Riboswitches produce an RNA conformation that prevents ribosome binding. Posttranslation/ Translation/ Transcription
5. Antisense RNA binds to the mRNA.Translation / Transcription / Posttranslation
6. The product of a metabolic pathway inhibits the first enzyme in a pathway.Posttranslation/ Transcription/ Translation
7. A protein is covalently modified. Posttranslation / Translation / Transcription

Write a typical scenario about a student just entering college trying to build a credit score

Making RNA from DNA is called _______. Making proteins from RNAis called _______.

Extend your thinking: Sometimes errors occur during transcription or translation. Examine the codon chart on the previous page. Notice that each amino acid is coded for by several different codons. For example, alanine is coded for by GCU, GCC, GCA, and GCG.

How might this offset transcription or translation errors?

Examine and discuss the concept of descent of all living thingsfro
A common ancestor. Compare relationship between DNA ofhumans,chimpanzee and gorillas

• Think and discuss: Consider the two following statements:

• The theory of evolution states that all living things had a single common ancestor.

• The translation between mRNA and amino acids is the same for all living things. (For example, the mRNA codon CAG codes for glutamine in all living things.)

Does the second statement support the theory of evolution? Explain why or why not.

If possible, discuss your answer with your teacher and classmates.

C. What About the Minority? In a democracy, the will of the majority is considered first. Even so, governments still respect the rights of the minority. Think of three ways to solve the following problem:

Your school's student government has money left over from last year. The students hold a vote to decide what to do with the money. Results show 58% of the student body wants to add an ice cream cart to the cafeteria. But the Lactose Intolerant and Proud of It Student Association opposes the decision. They say it would be unfair to spend the money on something not all the students could enjoy.

The student body is looking for a compromise that follows the will of the majority but respects the needs of the minority.

In our ecology lab we focused on what happens over time after you disturb an ecosystem. Some ecosystems are maintained by periodic disturbance and without that disturbance the ecosystem may disappear altogether. The longleaf pine ecosystem is maintained by periodic fires. It is now an endangered ecosystem. Give a detailed description of the longleaf pine ecosystem including what species live there, how the ecosystem functions and is maintained. Also, describe where it existed historically, where it exists now, why it is endangered and what efforts are being made to reestablish it.
