If the sequence on a strand of a DNA molecule is C C C A C G T C T, what will the mRNA sequence from this DNA molecule be?
mRNA strand transcripted assuming this is from 5' to 3':
For RNA complementary pairs are:
Let's assume that the
We notice that cytosine
And so, the complementary strand will start
Change all the letters into their complementary counterparts, we get,
Hope this helps!
If we assume this is the top strand (on the 5 prime end),then the mRNA sequence will be the same as this sequence, except U in place of T, since the mRNA is transcribed off the bottom (complementary) strand. And the complement to the complementary strand is the same as the top strand.
mRNA is made off of the 3-5 piece of DNA, and the RNA polymerase places the complement to the strand (i′ll put mRNA in lowercase)
