Question
The following segment of DNA is from a transcribed region of a chromosome. You know that RNA polymerase moves from left to right along this piece of DNA, that the promoter for this gene is to the left of the DNA shown, and that this entire region of DNA is made into RNA.
5-GGCATGGCAATATTGTAGTA-3
3-CCGTACCGTTATAACATCAT-5
Given this information, a student claims that the RNA produced from this DNA is:
3-GGCATGGCAATATTGTAGTA-5
Select all reasons why this answer is incorrect.
a) The RNA molecule should match the bottom strand of DNA, only with uracil instead of thymine.
b) The polarity of the molecule is incorrectly labeled.Explanation / Answer
b) the polarity of the molecule is incorrectly labeled.
c) the RNA molecule should have uracil instead of thymine bases.
