How do you deal with procrastination?

[Lou]

I have a lot of things to do but I don't feel like doing them. Write me a nice essay, 2 or 3 sentences long, explaining how you deal with procrastination. thanks

The accompanying figures give maps and partial DNA sequence data for the yeast expression vector pGAPZA (a shuttle plasmid, propagated in E.coli, which is incorporated into the yeast genome by homologous recombination on transformation into Pichia pastoris), and the cDNA cloning vector pBlueScript SK- (derived from the lambda vector ZAPII by plasmid excision). In addition, sequence data for a transcript produced by Drosophila melanogaster gene CG13095, thought to encode an aspartic proteinase, is given. The transcript encodes a preproprotein; the signal peptide is removed co-translationally, and the proteinase is activated by post-translational removal of an N-terminal pro-region. Assume a full-length cDNA corresponding to the CG13095 transcript has been cloned into pBluescript SK- using a directed cloning strategy, which adds linkers to the 5’ and 3’ ends of the cDNA as shown in the strategy diagram given.

You wish to investigate the specificity of proteolysis of the aspartic proteinase encoded by CG13095. Describe a strategy for using Pichia pastoris to produce recombinant proproteinase, and for purifying the recombinant protein for subsequent activation and assay. Your final product can have extra residues at the N-terminus compared to the protein produced in Drosophila, because these extra residues do not interfere with proprotein processing, and are removed when the proprotein is activated. A C-terminal “tag” is also acceptable, as results with expression of similar enzymes as recombinant proteins have suggested it does not interfere with activity.

Give sufficient details of the operations you propose to enable a competent but unimaginative technician to carry out the experiments. Describe the expected results after each step, and outline how you would verify that each step of the procedure had proceeded as expected. You should give exact details of DNA sequences used, and provide (partial) sequence data for the final expression construct which shows how the coding sequence fits into the expression vector.

Why do you think this expression host and vector were chosen? Can you see any potential problems with the system?

(Hint 1: you will need to assemble a composite sequence showing how the protein and nucleic acid sequences fit together. You can do this by electronic or physical cut and paste.)
(Hint 2: a font with uniform character widths – Monaco or Courier – makes producing a “lined-up” nucleotide and amino acid sequence a lot easier . . .)
(Hint 3: start with the cDNA assembled into its cloning vector. You can use this as a basis for preparing restriction fragments for restriction-ligation, or as a template for PCR. Assume your technician knows about cloning PCR products into an intermediate vector – such as pCR2.1 – for checking, and to avoid having to ligate directly after PCR and restriction.)
(Hint 4: the whole business is very much easier if you work out what you want to end up with first . . .)

CC Sequence submitted by:
CC Berkeley Drosophila Genome Project
CC Lawrence Berkeley National Laboratory
CC Berkeley, CA 94720
CC This clone was sequenced as part of a high-throughput process to
CC sequence clones from Drosophila Gene Collection (Rubin et al.,
CC Science 2000, Stapleton et al., Genome Biology 2002). The sequence
CC has been subjected to integrity checks for sequence accuracy,
CC presence of a polyA tail and contiguity within 100 kb in the
CC genome. Thus we believe the sequence to reflect accurately this
CC particular cDNA clone. However, there are artifacts associated with
CC the generation of cDNA clones that may have not been detected in
CC our initial analyses such as internal priming, priming from
CC contaminating genomic DNA, retained introns due to reverse
CC transcription of unspliced precursor RNAs, and reverse
CC transcriptase errors that result in single base changes. For
CC further information about this sequence, including its location and
CC relationship to other sequences, please visit our Web site

Notes
1) “CDS” above refers to the coding sequence, which runs from nucleotides 22 (start codon) to 1140 (stop codon).
2) The sequence given corresponds to a full length cDNA. (Note the poly(A) tail at the 3’ end of the mRNA.) Assume the linkers for cDNA cloning fit directly onto the sequence given.
3) In the translated sequence given, amino acids 1-17 correspond to a predicted signal peptide (see http://www.cbs.dtu.dk/services/SignalP/), which is removed co-translationally in vivo (in Drosophila). The protein product after translation starts at amino acid 18.

i have to do that, write up a practical and do another piece of work. All in for FRIDAY.............................FUCCCCCCCCCCCCCCCCCCCCCCCCCK!!!!! I am so up shit creek. For procrastination, unpug the internet, tidy your room, put anything playable in another room/sit in a different room. Then do it, I cannot strees ow much to just do the effing piece of work. DO IT! Don;t wait, it's not worth it, at all, really! PLEAS DO TI!

Dude you said the t word

 

[Qonfused]

I don't. And that's probably why I'm doing so bad in my studies.

 

[Ikerous]

Smoke, weed.

molecular biology and biochemistry

i have an exam tht doens't count at 9, but i am worried!

 

[bryanf445]

well if its the night before i have to turn something in adn its not done, i dont game or anything and finish it. The best way i deal with procrastination is to just suck it up adn do it.

 

[spookymooky]

Don't go to this site! You'll just end up waiting for the next interesting post!

 

[el Chi]

Don't "deal" with it. Embrace it. Revel in it. Submerge yourself into refining the delicate art that is procrastination - an extremely important quality for life.

 

[Vegeta897]

Consider what will happen if you don't do it. Run that through your head over and over until you fear it so much that you MUST do whatever you have to do.

Actually, this thread reminds me an idea I had. See, life is like a gang-bang porno. The last one to come gets there in the end. The first one to show up risks getting it in the behind.

I'm pretty sure this is an argument for procrastination, but I'm too lazy to find out.

 

[Absinthe]

I don't deal with it. Thus I'm ****ed for life.

 

[Shamrock]

Best way to deal with procrastination especially on a paper is to write a paragraph or page, whichever you prefer, a day until the paper is due. Lets say you have a 4.5 page paper due in a week. Write one page today then the next day write another page and so forth. I try and do that. Lately, I have been doing that with success.

Dealing with procrastination is very difficult. I've thought a lot about the matter, and there really is NO logical justification to not procrastinate and do your work at the immediate time.

Basically I just make myself zealously start doing work. Just starting is the hardest part.
