OpenStax is a good online textbook
https://cnx.org/contents/jVCgr5SL@15.47 ... troduction, you can also check Soinc.org's Internet Resources PDF link for some more internet links.

Will we be tested on cell cycle regulation?

Sorry for the triple post, but I have a question. So my partner and I were taking a test and we came across this question:
4. Which sequence of mRNA is produced from the transcription of DNA with the following coding strand sequence:
5' AATGGCACAGGTTCG 3'
a. 5' AAUGGCACAGGUUCG 3'
b. 5' UUACCGUGUCCAAGC 3'
c. 3' UUACCGUGUCCAAGC 5'
d. 3' CGUUCCUGUGCCAUU 5'
My partner and I thought the answer would be C, but it actually is A. Can somebody please explain why?

d. 3' CGUUCCUGUGCCAUU 5'
My partner and I thought the answer would be C, but it actually is A. Can somebody please explain why?
The answer C is if the sequence given was the
template strand, which is the strand the mRNA sequence determines its nucleotide sequence from. The coding strand is complementary to the template strand. This means that the sequence given in the question needs to be converted to the template strand first, then the mRNA sequence (or all in one step, just replace T with U). For any given gene, the template strand is always used to create the mRNA strand.
Hope this clears things up!

Hey does anyone know what some good online resources are, for heredity?

I've been using Khan Academy - try the High School Biology course
