MRNA sequence augccaaaaauugcgacuuag was transcribed from what DNA sequence?

That mRNA sequence had to come from the complement to it. Remeber that the sequence is normally read 5' to 3'. The complement that produced it would be seen in the 3' to 5' orientation (reverse) during transcription. Therefore, find the complement source by reading the sequence in reverse and making the following substitutions: a becomes t, u becomes a, g becomes c, and c becomes g. The result is the following DNA source sequence read 5' to 3': ctaagtcgcaatttttggcat.


What is the next number in the sequence 3.3.5.4.4?

3.3.5.4.4.6 It seems that the sequence takes the doubled numbers than adds two to the said number, such as five. So with that theory it would be logical that six would come after the doubled fours.

It is impossible to say what sequence comes after the given set of numbers. What I can do is to suggest what number might come next in the given sequence.Using the ruleUn = (7n5 - 129n4 + 891n3 - 2859n2 + 4298n - 1488)/24 for n = 1, 2, 3, ...the next number is 85.


What number should come next in the following sequence 6 9 8 11 10 13 12?

The sequence goes (starting from the six): Up 3: 6 + 3 = 9 Then you subtract 1: 9 - 1 = 8 Then you add 3 again: 8 + 3 = 11 then subtract 1 again: 11 - 1 = 10 The sequence is up 3, minus 1. You subtract 1 from 13 to get the 12, then you have to add 3 again. 12 + 3 = 15 15 comes next. Hope I helped! - Darg

What is the next number in this sequence 7 11 13 21 25 41 49?

Any number can come next in the sequence. Given ANY number, it is possible to find a polynomial of order 7 that will generate the above numbers and the chsen extra number. And polynomials are not the only kind of functions. However, the polynomial of order 6 that will fit these data is Un = (-53n6 + 1245n5 - 11525n4 + 53355n3 - 128462n2 + 150960n - 63000)/360 for n = 1, 2, 3, ... and, accordingly, the next number in the sequence is -175.
