The following mRNA fragment is responsible for coding exactly three amino acids, the 33rd, 34th, and 35th ones of a polypeptide that is made of 60 amino acids. The base sequence in this fragment is: ...AUGACUGAAUAA… Use the genetic code to name the amino acids in the order of addition to the growing polypeptide chain.

You are growing C3 and C4 plants in normal (21%) and low (1%) O2 air, under both warm well-lit conditions and cool shady conditions. You find that, in general, the C3 plants have a photosynthetic advantage over C4 plants in:
|
warm high light at 1% O2 and cool shade at 21% O2 only |
||
|
warm high light at 21% O2 and 1% O2, and cool shade at 21% O2. |
||
|
cool shade under 21% and 1% O2, and in warm high light at 1% O2. |
||
|
cool shade at 21% O2 and warm high light at 21% O2. |

For the experimental background, we treated 3T3 mouse fibroblasts with EGF and are now trying to detect the phosphorylated tyrosine proteins using primary and secondary antibodies as stains. We also made 4 different samples (a control with no EGF, a sample exposed for 1 minute to EGF, a 5 minute, and a 10 minute).
1) What does the appearance of a new band in a western blot mean?
2) When a band on a western blot increases in density over time, what does it mean?
3) When a band on a western blot decreases in density over time, what does it mean?
4) As it relates to EGF signaling, what process in the cell would possibly lead a band to increase in density over time?
5) As it relates to EGF signaling, what process in the cell would possibly lead to a band to decrease in density over time?
6) Why would a control (or 0 time) sample show bands for tyrosine phosphorylated proteins?
Thank you!

What is our current state of knowledge on DNA.
What Links genetic characteristics to DNA structure.
What are the steps in the process of protein synthesis.
How can it be that DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics in the organism.
How can interference in protein synthesis can result in disruption of cellular and bodily processes?

All plants use the Calvin Cycle to incorporate CO2 into simple sugars. C3 plants (typical plants) obtain their CO2 directly from the atmosphere but not without a cost. Explain this trade-off. What do C4 plants and CAM plants do differently (in general) and why do they do it? Where do these species typically live? Why don’t all species use the C4 or CAM photosynthetic process? In other words, what is the cost of doing C4 or CAM photosynthesis?
