My simulation is about the synthesis of mRNA from DNA. I need to work with random DNA sequences so I need to know if there are any "illegal" sequences. What would happen if you have multiple start codons before the next stop codon (overlapping)? You can assume the simplest form of transcription...

Thanks

Dear all, I'm studying DNA-Protein relationships for a computer simulation I have to make about it and I'm finding it difficult to understand how the RNA polymerase knows where to start and stop transcription on a strand of DNA. Could someone explain this for me? Let's assume that '['...

I'm programming in Java and using the Random class and I'm not sure if it makes a difference whether I use a single accessible Random object for the whole program or if I should create multiple instances (one for each object needing it?). Are there disadvantages to using one instead of the...

that's what I do but I need to see how much space will be required for text to show in flash using php. since flash uses pixels and php uses points, the dimensions will not match.

but that only works with monospaced fonts. I need a way to change size type.

php uses points (using gd2)... but I have no idea how to change the units in either php or flash...

Are you sure that Flash uses pixels rather than points? Well that would explain it... Although on some tutorials I found it uses points...

Has anyone noticed that the font size for Flash and the font size for GD images in PHP don't give the same text size?

! It works! Now why would that happen if I'm not using simulate download? Thanks sooooo much! I've posted this on 4 foraa and this is the only one I got an answer from... PF rulez!

I think I found a bug in Flash. It spans from CS3 to MX and perhaps earlier. I did a stop motion animation of me turning the pages of a scrap book (frames of a video recording). Then I put labels on each frame where a page is completely turned and did some actionscript (gotoAndPlay) so that I...

Oh ok, it's clear now. Thanks!

Is it even possible for something to spiral down into a planet, as in goes round and round and lower and lower until it crashes?

Oh, so every trajectory is an elliptical path, and the faster a projectile goes, the larger the ellipse until it is larger than the earth. Correct?

Not sure what the curvature of the Earth has to do with it because gravity will still pull the projectile towards the surface, but wouldn't that just result in a spiral towards the Earth then? Perhaps the answer would help me understand why comets don't just go straight into the sun as they...
