A strand of DNA has the base sequence GCTTAG. Write down the base sequence for the complementary strand. Keep in mind that the DNA and RNA strands are written from the 5' to the 3' end.
Name the function which does the "leader sequence" have in RNA translation. What would happen if it were missing? Does this protein require a leader sequence?
DNA (3.5 x 108 base pairs) in diploid cells of Drosophila melanogaster is replicated in around 3 minutes. Supposing that all replication forks move at a constant rate of 104 base pairs per minute an
When a single polypeptide chain protein has 185 amino acids, then what is the smallest number of mRNA nucleotides which could code for this protein? Explain how is this computed?
Will a change in a single DNA nucleotide (that is, a nucleotide substitution mutation) always outcome in a changed protein? Explain why or why not?
1) Explain, in general terms, the steps comprised in the automated synthesis of the DNA sequence GCT. 2) Draw and label the four DNA nucleosides.
Describe two of these four principal organic molecules. Where do you encounter these groups in your day by day life, and describe their significance to your body.
Knowing the sequence of a protein, a scientist synthesizes the corresponding RNA. By using the machinery of a cell and this RNA, the scientist then re-synthesizes the protein.
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.
