mRNA strand sequence question?
Sometimes a mistake ocurs in the translation of an mRNA strand. Suppose that the reading of the mRNA strand began, by mistake at the second nucleotide instead of the first. Write the sequence of amino acids that would be formed from N-Terminus to C-Terminus
mRNA sequence:
5' UAC GGG CGA VAG GCU GCU AUU 3'
Update:ok, it is not a V, it is a U nucleotide. :) My bad.

this is what's called a frame shift mutation. the reading would begin at the second pair and would group the base pairs as follows:
ACG GGC GAV AGG CUG CUA UU
and you can then look up which amino acids are coded by those three letter sequences.
it is fairly elementary fairly. You persist with the T-A, G-U rule. In DNA, G continually couples with C often of thumb and T with A. In RNA C is replaced via u.s. that G couples with U in RNA. The sequence you gave as a result interprets to: ATGUUAGATGUUAUUAAGGUTAA (mRNA sequence) TACGGTCTACGGTAGGTTCCGATT (DNA sequence)
