Design a non-natural base which will pair with thymidine with around equivalent strength to a GC base pair. Show the pairing interaction. No de novo synthesis is given.
Pertaining to the purine biosynthesis pathway of the mammalian cells, write down one illustration of a drug which inhibits a specific step of this pathway, the method of action, and how the drug is
Explain the processes of transcription and translation. Correctly recognize the anticodon for the given DNA template strand: ACG TGG GCA TGA ACG TGG.
Compare and contrast the similarities, differences and functions of the DNA and RNA.
Explain why do we use 16s rDNA for sequencing? Explain why do we use the nanodrop on our DNA extracts?
a) Write down two distinguishing features of a tRNA molecule. b) In translation what does the ribosome do?
In an actin assembly and a microtubule polymerization, whenever an ATP/GTP cap is formed, what do you mean by "stabilizing" the microtubule or microfilament?
List out three things you could do that would shift the dynamic equilibrium of an in vitro preparation of tubulin and microtubules toward the formation of microtubules.
Because cytoplasm vesicles are seen to move in both the directions in an axon, can you conclude that some of the microtubules are oriented with their plus end facing the axon terminus and others ori
Myosin action distinct from that of kinesin in that one of the kinesin heads is always in contact with a microtubule, while both myosin heads become completely detached from the actin filament.
I have been assigned the cell wall, and cell membrane for the biology project. One feature of the project is finding out the chemical equations for the processes which take place within that organel
If you were distinguishing the molecular structure of kinesin and dynein, which part (heads or tails) would you expect to be most similar between them? Explain why?
What does the method of chemiosmoisis in the chloroplast comprise? What about the method of mitochondrion? These areas are comprised.
What would be the result on the size of a cell membrane when the secretory pathway is active? Will this cause a problem for the cell, and what may a cell do to keep this from becoming a problem?
What benefit does such compartmentalization recommend a large cell and what are two illustrations of organelles and the activities they compartmentalize?
Both types of EM utilize some sort of metal coating, thus how do you describe that one kind (transmission) generates a two dimensional image and the other kind (scanning) produces a three dimensiona
Describe what happens to NAD.2H produced throughout the glycosis: a) In an animal cell respiring aerobically, and b) In an animal cell respiring anaerobically.
Consider the function of coenzyme NAD in glucose oxidation. In the method of glycolysis the formation of pyruvate comprises the reduction of the coenzyme NAD to NAD.2H.
Compare and contrast the repressive effects of chromatin and DNA modifications with the repressive effects of RNAi. Comprising:
You have been provided a picture of a cell. The magnification of the picture is 8000 X. The cell in this picture is 2 cm in length. Based on the information given, this job finds out what is the rea
Bread ingredients comprise milk, sugar, flour and salt. Which of these is required for maximum fermentation by the yeast? What tests could be done in the lab?
The integrity of the plasma membrane is necessary for cellular survival. a) Could the immune system use this fact to destroy foreign cells which have invaded the body?
In what sense can I claim that the inner surface of the nuclear envelope, the ER, of vesicles and of the Golgi cisternae is really connected with the outside of the cell?
I am presently studying the intracellular distribution of a particular protein. The protein is usually Golgi-resident. What would happen to this distribution if I treated the cell with an inhibitor
You make radioactively labeled ribosomal subunits and you microinject them to cells which you are culturing in the laboratory. At different times after you inject the subunits, you take a small amou
