You have been asked to make a presentation to the International Environmental Conference 2009.

Describe the three key points that you would make in your presentation.

consider the structure of the neurotransmitters: Acetylcholine, Noradrenaline, Adrenalin, dopamine, glycine, serotonin, y-aminobutyric acid and glutamic acid and suggest what type of binding interactions could be involved in binding them to a receptor binding site, and identify possible amino acids in the binding site which could take place in these binding interactions

What orders of insects are primarily wingless? Of these, which orders are primitively wingless (never evolved wings) and which have evolved winglessness from winged ancestors? What are the advantages and disadvantages of being wingless?

*please include link to any thing cited in your answer so I may reference any resources for more information

How would you measure the insect biodiversity of the lesser prairie-chicken habitat? Explain your steps.

Choose just one of the following concepts:  evolution, competition, biodiversity or biogeochemical cycling. For each level of biological organization in the table below, explain an aspect of your chosen concept that is specifically relevant to that level of organization.

1. The high ____________ and ____________ of water makes it stable as a liquid over a large range.

2. The allosteric site in enzyme results in this type of regulation

3. Carbon and hydrogen alone form hydrocarbons, which with respect to the interaction with water may be defined as

4. This organelle in eukaryotic cells may put into vesicles molecules originally produced in another organelle

Thank you very much in advanced!

Compare and contrast how plants and animals use hormones to control life processes.

- how is it related to the ecosystem?

- the effect of pollution on this.

Hi, I in Human Genetics.discussing questions on the single gene trait dwarfism and how ir relates to dominand and recessive gene alleles.

My question is:

When discussing how dominant gene alleles and recessive gene alleles determine expression of single-gene traits, such as dwarfism, what are the current prognostic, diagnostic and treatment capabilities for dwarfism? Thank you!

describe the path that air takes as it enters and passes through the human respiratory system. pls help

Data Tables and Post-Lab Assessment

Lab Questions

1.     Transcribe the following DNA sequence:

Hb A:

5’ AGT AAC GGC AGA CTT CTC CTC AGG AGT CAG GTG CAC CAT 3’

3'UCA UUG CCG UCU GAA GAG GAG UCC UCA GUC CAC GUG GUA 5'

2.     Translate your new RNA sequence using the genetic code. Remember that when determining your amino acid sequence, the RNA sequence is read from 5’ to 3’.

val- val -his- val- ser -ser- glu- glu- ser-ser- pro- leu -ser

Note: the first amino acid will be Met.

3.     Transcribe the following DNA sequence.

Hb S:

5’ AGT AAC GGC AGA CTT CTC CAC AGG AGT CAG GTG CAC CAT 3’

3`UCA UUG CCG UCU GCC GAG GUG UCC UCA GUC CAC GUG GUA 5`

4.     Translate your Hb S transcript.

val- val- his- val- ser-ser-val-glu- ser- ser- pro- leu - ser

Note: the first amino acid will be Met.

Post-Lab Questions

1.     How long are each of your peptide chains (how many amino acids are present)?

The proteins are made up of multiple units of amino acid. When we talk about peptide

chains they are combination of multiple amino acids. Each of the peptide chain consists

of many amino acids and the number varies.

2.     What differences exist between your two transcripts? What about your translated product?

3.     Hb A represents a section of the 626 base normal hemoglobin beta mRNA sequence. Hb S is from the sickle cell hemoglobin. Is the mutation found in sickle cell hemoglobin a point mutation or a frameshift mutation?

4.     Does the sickle cell mutation result in a missense mutation, silent mutation or nonsense mutation? Why?

A missense mutation is the cause of the disease, sickle cell anemia In a missense mutation, a change in one base pair causes a single amino acid to be changed in the resulting protein. In sicle cell anaemia there is missence mutation in ?-globin gene where glutamic acid (E/Glu) being substituted by valine (V/Val) at position 6.

Description: Unnatural amino acid mutagenesis might be one of the most groundbreaking achievements in modern biochemistry. This process allows for the incorporation of amino acids not coded for by the body (one's different from the 20 amino acids you studied in this course). This process allows scientists to use amino acids with different functional groups not found in nature.

Instructions: You will investigate how unnatural amino acid mutagenesis works. Take time to examine what changes needed to be made to the tRNA to allow for an unnatural amino acid to be used instead of the native substrate. Also focus on what codons are used to recognize the modified tRNA. How many different codons are there that can be used? What are they called? Please cite any sources used in this discussion (should contain 5-10 sources). This paper should be around 1-3 pages and cover a good deal of detail on how this process works. If you would like to submit early, I would be more than happy to look over it and return it with some suggestions.

How can you use synonymous and non-synonymous mutations to distinguish drift, purifying selection and positive selection from one another?
