    Given a DNA sequence, which will be its mRNA?

    And what will be the peptide sequence formed? So the sequence is: ADN 3’- TAC-CGA-TAT-AGC-CGT-ATT -5’ so my guess is that it's AUG-GCU-AUA-UCG-GCA-UAA and the peptide sequence is: Start codon, alanin, isoleucine, serine, alanin, stop codon. My question is: What do those 3's and 5's mean...

    Help with linear transformation problem with variables

    Let L: R3 -> R3 be L(x)= \begin{pmatrix} x1+x2\\ x1-x2\\ 3x1+2x2 \end{pmatrix} find a matrix A such that L(x)=Ax for all x in R2 From what I understand I need to find the transition matrix from the elementary to L(x). However it is'nt a square matrix and it has variables instead of numbers...

    How to solve a system with more unknowns than equations?

    Because if you reduce to Row-Echelon form you don't end up with a triangulated form. Here is what I ended up with (How do I use Latex Reference to construct a Matrix? Can someone help me with that by the way please?) 1 -1 3 2 | 1 0 1 1 3 | -1 0 0 1 1 | -1

    Is it possible to find the SD without the data?

    Oh yeah, I forgot to say it's a normal distribution. I used the invNorm function to see which standard deviation best models the situation, so I found out that 0.36 does it pretty well. So the value I got for the 90th percentile is more of an estimate (4.26), but I think it fits well enough.

    Is it possible to find the SD without the data?

    I have the mean and I have the value at a percentile (99th percentile to be specific). I am just wondering if it's possible to find the SD. Actually, what I am trying to find is the value at the 90th percentile (I think I need the SD to do it, but maybe just maybe there's another method...)...

    Programs Computer Engineering Degree without an undergrad?

    OK Thanks. Other than learn the topics of interest by myself and have several web-business projects as long-term projects, what else would you recommend (I'm only 18 right now, I can plan ahead lots of things) to overcome that barrier?

    Java [Java] what's wrong with my bubble sort algorithms?

    I have 2 possibilities, non of them worked: PD: I am sure that all the methods inside this method(s) are correct and I am sure that the program's GUI is refreshing effectively. public void metodo1() { for (int i=0; i<(perros.size()); i++){ for (int j=perros.size()-1...

    Rotational Motion: Energy Conservation

    Use the fact that W=ΔEk So you get: h=separation between photogates a=acceleration of the system m=mass of the block moving through the photogate M=mass of the other block v=velocity of the system mah=0.5m(v22-v12) So the only thing you need to know in order to solve for v2 in...
