Re: Plz help - question on probabilty of a nucleotide sequence

... of that sequence occuring in a row: (.31)(.31)(.19)(.19)(.31)(.31) = 0.0003339 But I think with this formula, the order doesn't matter, rigth? So, permutation of a sequence which has 6 elements with two repetitions (As and Ts): 6!/(2!).(2!)=180 Which means there are 180 permutations of 6 bp sequence ...

Probability Genetics question

... this way instead of saying 20%. I think the order is important. Because, each subsets of a combination is a different event. Thus, we should use permutation instead of combination. In other words, if someone says 'families that have 2 boys and 2 girls', we consider every familiy with this condition ...

Re: General questions about Haemoglobin molecule

... acid chain. Its chemical formula been : C738 H1166 N812 O203 S2 Fe Using the formula of specificity, calculations show there are 1x10^650 possible permutation possibilities. In a living human, only 20 amino acids can be selected (and only left handed ones) in order for the Haemoglobin to work effectively. ...
